Kinetic Theory and combined Gas Laws (Chemistry) 21-22

How could you make the stopper pop out of the flask?

• Decrease pressure
• Decrease temperature
• Increase volume
• Increase temperature

According to the kinetic theory of gases, gas particles

• Do not always move in straight lines

• Have most their volume occupied by empty space

• Attract each other

• Do not always move randomly

Gas pressure is caused by

• Molecules colliding with each other

• Molecules condensing to a liquid

• Molecules colliding with the walls of containers

• Barometers

What happens to the average kinetic energy of matter when it is heated?

• It increases
• It decreases 
• It doesn't change
• It cannot be determined

Gas molecules can easily be compressed  because ___________. 

• gas molecules are soft
• gas molecules are far apart
• gas molecules follow the shape of the container

Which container will have lower pressure?

• left
• right
• they both have the same pressure

If a gas with an odor is released in a room, it soon can be detected across the room because

• the gas can diffuse
• the gas is dense
• the gas is compressed
• the gas condenses

According to kinetic molecular theory-Gas molecules influence each other only by collision; they exert no other forces on each other.

• True

• False

According to the kinetic molecular theory, the volume actually occupied by the molecules of a gas is negligibly small; the vast majority of the volume of the gas is empty space through which the gas molecules are moving.

• True

• False

• Flask 1 contain the most molecules
• Flask 2 contain the most molecules
• Flask 3 contain the most molecules
• Flask 4 contain the most molecules
