Linda inflates and ties off a balloon in her classroom and then takes it outside on a cold, winter day. Within 10 minutes, she notices that the balloon has gotten a little smaller. Why does this occur?
Because there are fewer molecules in the balloon in the colder, outside air
Because the air pressure is significantly higher when it is colder
Because the molecules in the balloon have slowed down with the decreased temperature
Because the molecules shrink in size when exposed to the colder, outside air
What is going to happen to the volume of a gas that is put under MORE pressure while keeping the temperature constant?
The volume will increase
The volume will decrease
The volume will fluctuate
The volume will remain constant
Carlos measured the tire pressure of his truck that was parked outside after a cold night. The daytime temperature reached a nice 65°F. Assume Carlos’ tires do not have any leaks. Explain the change in tire pressure.
The air molecules heated inside the tire causing them to move faster, exerting more pressure on the inside walls of the tires.
The air molecules heated inside the tire causing them to move faster, exerting less pressure on the inside walls of the tires.
The air molecules heated inside the tire causing them to move slower, exerting more pressure on the inside walls of the tires.
The air molecules heated inside the tire causing them to move slower, exerting more less on the inside walls of the tires.
When the burner in a hot air balloon is turned on, the temperature of the air in the balloon (increases or decreases) (a) , causing its volume to (expand or shrink) (b) and the balloon to (rise or fall) (c) .
If the pressure of a sample of gas is doubled at a constant temperature, what happens to the volume of the gas?
The volume doubles
The volume is halved
The volume quadruples
The volume remains constant
Explain why a this chip bag nearly popped when it was taken up a mountain.
The decrease in atmospheric pressure allows the bag wall to become more elastic.
The decrease in atmospheric pressure (relative to pressure inside the bag) causes it to expand
The increase in atmospheric pressure pushes the walls of the bag outward, thus making it larger
The increase in atmospheric pressure forces the gases to push harder on the bag increasing its size
A decrease in the density of a sample of gas inside a balloon could be caused by ___.
Putting the balloon in the refrigerator
Taking the balloon outside on a hot day
Shaping the balloon into the shape of a dog
Taking the balloon down to the bottom of a swimming pool
Demarius was given a marshmallow and a syringe in class to experiment with. She placed the marshmallow in the syringe and sealed the end. When she decreased the pressure inside of the syringe, what happened to the marshmallow and why?
The decreased pressure pushed the molecules closer together and caused the marshmallow to shrink.
The decreased pressure allowed the molecules to spread apart and caused the marshmallow to grow larger.
The decreased pressure created an increase in temperature and the marshmallow expanded
Nothing happened, as there is no relationship between pressure and the size of the marshmallow
How is the temperature of a gas related to the kinetic energy of its particles?
As the temperature extends, the kinetic energy of the particles decreases
As the temperature increases, the kinetic energy of the particles increases
As the temperature decreases, the kinetic energy of the particles increases
As the temperature intensifies, the kinetic energy of the particles decreases.
Given the diagram showing gas molecules in different containers, a reasonable inference could be made that there is a relationship between ___.
Volume and pressure
Temperature and volume
Temperature and density
Pressure and temperature
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 remain constant
The pressure will equalize

Stay the Same
When Temperature of a gas increases, the Pressure will ____________________
Increase
Decrease

Which graph shows the correct relationship between the volume of a gas (V) and its absolute temperature (T), when pressure is held constant?
Which graph represents the relationship between pressure and volume for a sample of an ideal gas at constant temperature?
Critical Thinking! If gas particles in a tire are moving slowly, your tire pressure will drop because the gas particles are not pressing against the walls of the tire. What temperature change do you think would cause this pressure drop?
The temperature will have become colder
The temperature will have become hotter
Temperature and pressure have no relation
The pressure of the gas in the balloon in the ice water will be:
Greater than that of the balloon in the boiling water.
Less than that of the balloon in the boiling water.
The same as that of the balloon in the boiling water.
