A balloon filled with helium occupies a volue of 1.50L at 752 torr and 25^oC. What will be the volume of the balloon at a pressure of 438 torr if there is no change in temperature?

• 752 torr

• Pressure 1= P₁

• This is what we are solving for.

• Pressure 2= P₂

• 1.50L

• Volume 2= V₂

• 438 torr

• Volume 1= V₁

In a typical automobile, the mixture of gasoline and air in a cylinder is compressed from 1.0 atom to 9.5 atm. If the uncompressed volume of the cylinder is 410 mL, what is the volume in mL when the mixture is fully compressed?

• This is what we are solving for.

• Volume 1= V₁

• 410mL

• Pressure 2= P₂

• 9.5 atm

• Volume 2= V₂

• 1.0 atm

• Pressure 1= P₁

A gas has a volume of 37.5mL at a pressure of 95 kPa. If the new pressure is standard pressure, what is the new volume?

Hint: Standard pressure is the pressure that is equal to 1 atm.

• 101.3 kPa

• Pressure 2= P₂

• 37.5mL

• Volume 1= V₁

• This is what we are solving for.

• Pressure 1= P₁

• 95 kPa

• Volume 2= V₂
