kinetic molecular theory

Gases are compressible.

• True
• False

The measure of the average kinetic energy of the particles of a substance is the 

• temperature
• heat
• thermal energy
• kinetic energy

The force of a gas's outward push divided by the area of the walls of the container is the gas's:

• pressure

• voulume

• temperature

• surface tension

The greater the speed of gas particles in a container, the:

• greater the pressure
• fewer collisions there will be
• lower the temperature
• lower the pressure

When the temperature of matter increases the particles...

• speed up and move closer
• speed up and move farther apart
• slow down and move closer together
• slow down and move farther apart
