Choose TWO of the basic ideas that are part of the kinetic molecular theory.

• the volume of a gas increases when the temperature increases at a constant pressure

• particles are in constant, random motion

• when particles collide, there is no energy lost

• the pressure of a gas increases when the volume increases, if the temperature is constant

Applying Boyle's Law, what would happen to a gas if the volume of its container decreased and the temperature stayed the same? The gas pressure would________________ .

• increase

• decrease

Charles' Law states that....

• the volume of gas becomes LESSER when the temperature goes up and pressure stays the same.

• small particles make up all matter

• the volume of a gas become GREATER when the temperature goes up and pressure stays the same.

• when particles collide, no energy is lost.

What happens when the motion of particles slows?

• the particles split

• the particles move further apart

• the particles move closer together

• the particles no longer move randomly

• rapid movement of particles

• attractive forces between particles

• crystalline arrangement of particles
