What happens to the solubility of carbon dioxide gas in a carbonated drink when it is cooled?
It increases.
It decreases.
It is not affected.
It can increase or decrease.
Answer explanation
The solubility of carbon dioxide gas in a carbonated drink increases when cooled. This is due to the decreased kinetic energy of the gas molecules, allowing more CO2 to dissolve in the liquid.

Which factor explains why a cube of sugar placed in water will dissolve at a slower rate than granular sugar over time?
The mass of the cube decreases.
The cube has a smaller surface area.
The temperature of the cube decreases.
The particles in the cube have more movement.
Answer explanation
The cube has a smaller surface area compared to granular sugar, which means fewer sugar particles are exposed to the water at once. This limits the rate at which the sugar can dissolve.

According to the graph, how much salt is expected to dissolve in 150 mL of water at 80°C?
30 grams
50 grams
70 grams
90 grams
Answer explanation
The graph indicates that at 80°C, 50 grams of salt can dissolve in 150 mL of water. Therefore, the correct answer is 50 grams.

What question would BEST help understand why the volume of water changes when it turns from a liquid to a gas?
A. How can the movement of the particles be described?
B. Which model has the most gas molecules?
C. Which model has the largest gas molecules?
D. How can the temperature of the particles be described?
Answer explanation
Choice A is correct because understanding particle movement is key to grasping how water's volume changes during the transition from liquid to gas. It explains the behavior of particles in different states.

A container of gas is held at a constant pressure. Which of these would cause the volume of the gas to decrease while the average kinetic energy of its molecules remains constant?
increasing the number of gas molecules inside of the container
decreasing the number of gas molecules inside of the container
decreasing the Kelvin temperature of the gas
increasing the Kelvin temperature of the gas
Answer explanation
Decreasing the number of gas molecules reduces the volume while keeping pressure constant. The average kinetic energy remains unchanged if the temperature is constant, as it is directly related to the number of molecules.

Why can gases be compressed more easily than liquids?
Because the particles in gases are closer together than in liquids.
Because the particles in gases are farther apart than in liquids.
Because gases have a fixed volume but liquids do not.
Because gases have a definite shape but liquids do not.
Answer explanation
Gases can be compressed more easily than liquids because the particles in gases are farther apart. This greater distance allows gases to occupy less space when pressure is applied, unlike liquids, where particles are closer together.

A balloon is filled with helium and released. The pressure decreases as the balloon rises. Which will most likely happen to the balloon as it rises?
The balloon will expand as it rises since the volume will increase.
The balloon will shrink as it rises since the volume will decrease.
The balloon will leak gas as it rises and the volume will decrease.
The balloon will not change as it rises because the volume is constant.
Answer explanation
As the balloon rises, the external pressure decreases, allowing the helium inside to expand. This results in the balloon expanding as it rises since the volume will increase.
