Which graph shows the relationship between pressure and Kelvin temperature for an ideal gas at constant volume?

• 
• 
• 
• 

A cylinder with a tightly fitted piston is shown in the diagram above. As the piston moves downward, the number of molecules of air in the cylinder

• decreases

• increases 

• remains the same

According to the kinetic molecular theory, which statement describes the particles in a sample of an ideal gas?

• The particles have attractive forces between them.

• The particles are considered to have negligible volume.

• The particles are constantly moving in circular paths.

• The particles collide, decreasing the total energy of the system.

As the temperature of a gas increases with the volume remaining constant, the pressure of the gas

• decreases

• increases

• remains the same

As volume of the gas in this container increases, pressure will

• decrease.

• remain the same.

• increase.

• I don’t know

If a hairspray can is heated, what can be expected of the pressure of the gas inside the can?

• The pressure will increase

• The pressure will decrease

• The pressure will remain constant

• The pressure will equalize
