A student inflates a balloon with helium then places it in the freezer. The student should expect
the balloon's volume to increase
the balloon's volume to decrease
the balloon's moles to increase
the balloon's moles to decrease
If a hairspray can is heated, what can be expected of the pressure of the gas inside the can?
The pressure will increase
The pressure will decrease
The pressure will remain constant
The pressure will equalize
Decreasing the pressure of a gas causes
increased volume
decreased volume
Increasing the temperature of a gas causes
increased pressure
decreased pressure
How is the volume of a gas related to the temperature?
They are independent of each other.
They are inversely proportional.
They are directly proportional.
They are negatively correlated.
A mass of gas is enclosed in a rigid container. What will occur if the velocity of the gas molecules colliding with the sides of the container increases?
The pressure will increase.
The density will increase.
The pressure will decrease.
The density will decrease.
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.
A child gets a helium-filled balloon. She then takes the balloon outside into the cold air. She notices that balloon deflates a bit. What most likely caused this to happen?
The air pressure inside the store was higher than the air pressure outside.
The cold air outside allowed some of the helium atoms to escape from the balloon.
The speed of the helium atoms decreased outside, causing the pressure in the balloon to decrease.
The air molecules outside were moving faster than the helium atoms, putting pressure on the outside surface of the balloon.
Jacob took an empty water bottle and put the lid on it. He then put the water bottle into a boiling water bath. After 5 minutes, Jacob removed the bottle and immediately placed it in a cold water bath.
Which of the following best explains what Jacob observed?
The water bottle collapsed because the volume increased as the temperature decreased.
The water bottle collapsed because the volume decreased as the temperature decreased.
The water bottle expanded because the volume increased as the temperature decreased.
The water bottle expanded because the volume decreased as the temperature decreased.
