A balloon containing helium gas has a volume of 2.44 L at room temperature 23 oC. The balloon is heated to a temperature of 78 oC. Assuming no change in pressure, what is the new
Answers
The new volume of the balloon when heated to 78 oC is approximately 2.89 L, assuming no change in pressure.
The volume of a gas is directly proportional to its temperature when pressure remains constant. This relationship is described by Charles's Law.
To find the new volume of the balloon after it is heated to 78 oC, we can use the formula:
(V1 / T1) = (V2 / T2)
where V1 is the initial volume, T1 is the initial temperature, V2 is the final volume, and T2 is the final temperature.
Given:
Initial volume, V1 = 2.44 L
Initial temperature, T1 = 23 oC = 23 + 273.15 K = 296.15 K
Final temperature, T2 = 78 oC = 78 + 273.15 K = 351.15 K
We can plug these values into the formula and solve for V2:
(2.44 L / 296.15 K) = (V2 / 351.15 K)
Cross-multiplying:
(2.44 L) * (351.15 K) = (296.15 K) * (V2)
V2 = (2.44 L) * (351.15 K) / (296.15 K)
Calculating:
V2 ≈ 2.89 L

Answers
(a) To get the pH of the media to 5.8, you would add NaOH solution. NaOH is used as a basic solution, and when it is added to a solution, it will increase the pH of the solution.
(b) The molecular weight of BA is 225.3. To prepare a 1M solution, you would have to weigh out 225.3 grams of BA.(c) To convert a 1M solution of BA to mg/mL, you can use the following equation: 1 mole = molecular weight in grams; 1000 millimoles = 1 mole. So, 1 M = 1000 mg/mL. Therefore, a 1M solution of BA is equivalent to 1000 mg/mL .(d) To convert a concentration of 1000 mg/mL .
Therefore, to calculate the weight required for a 5 mM solution, use the following formula :Mass of BA = molarity × volume × molecular weight= 5 × 0.001 × 225.3= 1.1265 grams(f) To convert a concentration of 5 mM to mg/mL, we use the following formula: Concentration (mg/mL) = (Concentration (mM) × Molecular weight) / 1000= (5 × 225.3) / 1000= 1.1265 mg/mL(g)
To convert a concentration of 1.1265 mg/mL to mg/L, we multiply by 1000, so 1.1265 mg/mL = 1126.5 mg/L.(h) Given that the stock solution of BA is 5 mM and the working solution is 0.2 mg/mL.

Does fertilizer make a plant grow bigger?mention two variables. How change of one variable effects another one in investigation?
Trick question
Science
Answers
In scientific investigations, the effect of fertilizer on plant growth can be studied by examining various variables. Two key variables in this context are the presence or absence of fertilizer (independent variable) and the size or growth of the plant (dependent variable).
When investigating the effect of fertilizer on plant growth, the independent variable is the presence or absence of fertilizer. This variable is controlled by having two groups of plants: one group receiving fertilizer (experimental group) and another group without fertilizer (control group). By comparing the growth of these two groups, we can determine the impact of fertilizer on plant size.
The dependent variable, on the other hand, is the size or growth of the plant. This variable is measured or observed as the outcome of interest. In this case, it would be the height, weight, or overall size of the plants.
By systematically changing the independent variable (presence or absence of fertilizer), we can observe how it affects the dependent variable (plant growth). The experimental group receiving fertilizer is expected to show greater plant growth compared to the control group without fertilizer. This allows us to draw conclusions about the effect of fertilizer on plant growth.
However, it is important to note that the specific outcome may vary depending on other factors such as plant species, soil conditions, and environmental factors. Conducting a controlled experiment while considering these factors helps in obtaining more reliable results.

Solids and liquids cannot be compressed as muc gases.
Answers
The kinetic theory is a fundamental concept in physics and chemistry that explains the behavior of particles in matter.
a. Wax melts near the flame of a burning candle: The heat from the flame increases the kinetic energy of the wax molecules, causing them to move more rapidly. This increased kinetic energy overcomes the intermolecular forces holding the solid wax together, leading to the transition from a solid to a liquid state.
b. Liquid water may be converted into ice cubes in a freezer: The low temperature in the freezer reduces the kinetic energy of water molecules, causing them to slow down and come closer together. With decreased kinetic energy, the intermolecular forces between water molecules become stronger, leading to the formation of a solid lattice structure and the conversion of liquid water into ice.
c. Ginger ale flows to match the shape of the glass: The kinetic theory states that the particles in a fluid, such as ginger ale, are in constant motion. The particles can move and flow, adapting to the shape of the container they are in. As a result, the ginger ale flows and conforms to the shape of the glass.
d. Water gradually evaporates from a swimming pool: The kinetic theory explains that molecules in a liquid have varying kinetic energies. At the surface of the water, some molecules possess sufficient energy to escape the intermolecular forces and transition into the gas phase, resulting in evaporation. This continuous process leads to the gradual loss of water molecules from the swimming pool.
e. Water vapor condenses inside house windows on cold days: When warm, moist air comes into contact with the cold surface of house windows, the temperature of the air decreases. The decrease in temperature reduces the kinetic energy of water vapor molecules, causing them to slow down and come closer together. As a result, the intermolecular forces become stronger, leading to the condensation of water vapor into liquid water droplets on the cooler windows.
f. Snow gradually disappears, even when the temperature remains below freezing: The phenomenon is known as sublimation, where solid snow directly transitions into water vapor without going through the liquid phase. The process occurs when snow gains enough kinetic energy from its surroundings, causing its molecules to increase their motion and transition into the gas phase, resulting in the gradual disappearance of the snow even at temperatures below freezing.
g. Solids and liquids cannot be compressed as much as gases: According to the kinetic theory, particles in solids and liquids are closely packed with limited space to move. The intermolecular forces between particles are strong, maintaining their fixed positions or limited motion. In contrast, gases have particles with higher kinetic energy, which allows them to move freely and occupy a larger volume. Therefore, solids and liquids have limited compressibility compared to gases.

In the titration of a weak monoprotic acid with a strong base, the pH of the titration solution halfway to the endpoint will be:
C. greater than the pKa of the weak acid.
During the titration of a weak acid with a strong base, the pH of the solution changes as the titrant is added. At the halfway point to the endpoint, the moles of strong base added are approximately equal to half the moles needed to reach the equivalence point.
Since the weak acid is partially neutralized, the concentration of its conjugate base increases, making the solution more basic. As a result, the pH at the midpoint of the titration will be greater than the pKa of the weak acid.

Answers
The change in entropy of the gas is 27.6 J/K.
Entropy of a gas:
Entropy of a gas is the measure of the disorder or randomness of the particles in a system. The second law of thermodynamics states that in an isolated system, the total entropy will always increase over time, indicating that the disorder of a system will always increase if it is left alone.
A diatomic ideal gas begins at a volume of 1.91 m3, a pressure of 105 kPa and a temperature of 21oC. It undergoes a constant volume process that triples its temperature. The change in entropy of the gas is J/K.
The relationship between entropy and temperature is given by:
\($$\Delta S = nC_{v}ln\frac{T_{2}}{T_{1}}$$\)
Where , ΔS is the change in entropy of the gas,
n is the number of moles of the gas,
Cv is the heat capacity at constant volume,
T2 is the final temperature of the gas and
T1 is the initial temperature of the gas.
Since the gas is diatomic, its heat capacity is given by:
Cv = 5/2R where R is the ideal gas constant.
Therefore, the change in entropy of the gas is:
\($$\Delta S = nC_{v}ln\frac{T_{2}}{T_{1}}$$\)
\($$\Delta S = n(\frac{5}{2}R)ln\frac{T_{2}}{T_{1}}$$\)
\($$\Delta S = (\frac{5}{2})(8.31)ln\frac{3T_{1}}{T_{1}+273}$$\)
At a temperature of 21oC, the initial temperature of the gas is:T1 = 21 + 273 = 294 K.
Substituting T1 into the equation gives:
\($$\Delta S = (\frac{5}{2})(8.31)ln\frac{3(294)}{294+273}$$\)
\($$\Delta S = 27.6 J/K$$.\)

Describe a method to investigate how the temperature changes when
different masses of ammonium nitrate are dissolved in water.
You do not need to write about safety precautions.
(6marks)
Answers
Answer:
Decrease temperature with increase in ammonium nitrate concentration.
Explanation:
The temperature changes when different masses of ammonium nitrate are dissolved in water because the ammonium nitrate takes energy from the surrounding water environment for the breaking of ionic bonds as a result the temperature of water decreases. When more concentration of ammonium nitrate is added to water, more decrease occur in temperature of water and the water becomes cold.
Hotness or a cold state of a substance or a solution is measured physically by temperature. It is measured by a device called a thermometer and can be in the form of Kelvin, degree Celsius or degree Fahrenheit.
Decreasing the temperature with an upsurge in the ammonium nitrate concentration can be used in determining the change in the temperature.
The change can be explained as:The alteration in temperature can be seen after adding more ammonium nitrate with various concentrations to the water.Ammonium nitrate accepts energy from the water present in its surrounding solution for splitting the ionic bonds present.This energy acceptance from water reduces the temperature of the water and with the increase in concentration lowers the water temperature more.Therefore, increased concentration reduce temperature.

Motor oil has different ratings depending on how readily it flows. This property depends on how much attraction is present between its particles. Which property of a liquid does this illustrate?
Answers
The intermolecular force of attraction in liquid molecules affect their flow as well their viscosity. As the viscosity of the liquid increases, its rate of flow decreases.
What is viscosity ?Viscosity of a liquid is the measure of resistance to its flow. The fluidity, a measure indicating the ease of flow, is the reciprocal of viscosity. For instance, molasses is more viscous than water.
Viscosity can be thought of as internal friction between the molecules; this friction prevents the development of velocity disparities within a fluid since a section of a fluid that is compelled to move carries along nearby parts to some extent.
When fluids are employed as lubricants and carried through pipelines, their viscosity plays a significant role in determining the forces that need to be overcome.
