Unit 9 Gas Laws Test Review

What is the relationship between the pressure and temperature of a gas?

• pressure increases, temp decreases

• pressure increases, temperature remains the same

• pressure increases, temperature increases

If the volume of a container containing gas is decreased, what will happen to the pressure within the container?

• Pressure will stay the same

• Pressure will decrease

• Pressure will increase

The proper units for the variables in the ideal gas law are

• Liters, degrees Celisus, watts, grams

• Liters, Kelvin, atmospheres, moles

• Liters, degrees Celsius, atmospheres, joules

According to the kinetic molecular theory, molecules of gas are

• constantly moving, fast, and randomly until a collision occurs

• Avoid collisions by changing directions

• Alternately moving and stopping

• constantly moving in orbits around other molecules
