Gas Law Test Review

What describes the motion of a gas molecule?

• Molecules are spread far apart

• Move in constant, random motion

• It will travel in a straight path

• All of the above

If pressure goes down in a container, what happens to volume when the temperature is held constant.

• Increase

• Decrease

If temperature goes down in a container, what happens to volume when the pressure is held constant.

• Increase

• Decrease

How would you convert 34^oC to Kelvin?

• K = ^oC + 273

• ^oC = K + 273

• K = ^oC - 273

• ^oC = K + 273
