Gas Relationships

Boyle's law :  The pressure and volume of a gas show a _____ relationship. 

• Inverse 

• Direct 

A student inflates a balloon with helium then places it in the freezer. The student should expect

• the balloon's volume to increase

• the balloon's volume to decrease

• the balloon's moles to increase

• the balloon's moles to decrease

Pressure is

• defined as the mass that an object exerts when at rest.

• not a measurable in gases.

• defined as the number of moles of substance divided by the mass of the substance.

• created by the force of the gas particles impacting the walls of the container.

• Increase

• Decrease

• Stay the Same
