1.

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?

a)

Because there are fewer molecules in the balloon in the colder, outside air

b)

Because the air pressure is significantly higher when it is colder

c)

Because the molecules in the balloon have slowed down with the decreased temperature

d)

Because the molecules shrink in size when exposed to the colder, outside air

2.

What is going to happen to the volume of a gas that is put under MORE pressure while keeping the temperature constant?

a)

The volume will increase

b)

The volume will decrease

c)

The volume will fluctuate

d)

The volume will remain constant

3.

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.

a)
  1. The air molecules heated inside the tire causing them to move faster, exerting more pressure on the inside walls of the tires.

b)
  1. The air molecules heated inside the tire causing them to move faster, exerting less pressure on the inside walls of the tires.

c)
  1. The air molecules heated inside the tire causing them to move slower, exerting more pressure on the inside walls of the tires.

d)
  1. The air molecules heated inside the tire causing them to move slower, exerting more less on the inside walls of the tires.

4.

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)   .

Choose from the below words
increases
decreases
expand
shrink
rise
fall
5.

If the pressure of a sample of gas is doubled at a constant temperature, what happens to the volume of the gas?

a)

The volume doubles

b)

The volume is halved

c)

The volume quadruples

d)

The volume remains constant

6.

Explain why a this chip bag nearly popped when it was taken up a mountain.

a)
  1. The decrease in atmospheric pressure allows the bag wall to become more elastic.

b)

The decrease in atmospheric pressure (relative to pressure inside the bag) causes it to expand

c)
  1. The increase in atmospheric pressure pushes the walls of the bag outward, thus making it larger

d)

The increase in atmospheric pressure forces the gases to push harder on the bag increasing its size

7.

A decrease in the density of a sample of gas inside a balloon could be caused by ___.

a)

Putting the balloon in the refrigerator

b)

Taking the balloon outside on a hot day

c)

Shaping the balloon into the shape of a dog

d)
  1. Taking the balloon down to the bottom of a swimming pool

8.

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?

a)

The decreased pressure pushed the molecules closer together and caused the marshmallow to shrink.

b)

The decreased pressure allowed the molecules to spread apart and caused the marshmallow to grow larger.

c)

The decreased pressure created an increase in temperature and the marshmallow expanded

d)

Nothing happened, as there is no relationship between pressure and the size of the marshmallow

9.

How is the temperature of a gas related to the kinetic energy of its particles?

a)

As the temperature extends, the kinetic energy of the particles decreases

b)

As the temperature increases, the kinetic energy of the particles increases

c)

As the temperature decreases, the kinetic energy of the particles increases

d)

As the temperature intensifies, the kinetic energy of the particles decreases.

10.
