The force of a gas's outward push divided by the area of the walls of the container is the gas's:

• pressure

• voulume

• temperature

• surface tension

In all gas laws calculations, temperature must be measured in

• Kelvins (K)

• Celcius (ºC)

• Farenheit (ºF)

Which of the following units is used to measure pressure

• K

• L

• moles

• atm

Which of the following is a unit used to measure volume?

• mmHg

• L

• K

• mol

What is the relationship between pressure and volume? Assume moles and temperature are held constant.

P1V1 = P2V2

• Direct - change in same direction

• Inverse - change in opposite direction

What is the relationship between temperature and volume? Assume moles and pressure are held constant.

V1/T1 = V2/T2

• Direct - change in same direction

• Inverse - change in opposite direction
