What about gasses can be measured?

• Pressure, number of molecules and Volume

• Temperature, Density Volume, and Pressure

• Volume, Density and Temperature

• Pressure, Temperature, Volume, and Number of molecules

If you increase the pressure of a constant volume of gas, what will happen to the temperature?

• Increase

• Decrease

• Stay the same

• It will Blow Up

What is the basis of kinetic-molecular theory?

• Molecules are in constant motion.
• Molecules only stop sometimes.
• Approximately half the molecules are stationary.
• It is impossible to tell if a molecule is moving or not.

• The pressure will increase

• The pressure will decrease

• The pressure will remain constant

• The pressure will equalize
