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

If you add gas particles to the container, what happens to the volume when the pressure and temperature 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
