Intro to Gases & Kinetic Molecular Theory

Which of the following units measure pressure?

• atm
• L
• K
• mol

Which of the following units measure volume?

• Kpa
• mmHg
• L
• K

Gas pressure is caused by

• gas molecules colliding with surfaces
• gas molecules condensing to a liquid
• gas molecules hitting other gas molecule
• barometers

• Gases do not move in straight line
• Most of the volume of gas is empty space
• Gas particles are not in constant random motion
• Gas particles attract each other
