Introduction to Gases/Boyle's Law

What is the new volume of the gas if the pressure on 350 L of oxygen at 720 mm Hg is decreased to 600 mm Hg?

• 420 L
• 29.2 L

• 292 L

A gas at a volume of 4.0 liters is at a pressure of 2.0 atm. The volume is changed to 16 Liters, what must the new pressure be?

• 2.0 atm

• 12 atm
• 10 atm
• 0.50 atm

The pressure on a sample of gas is increased from 1.0 atm to 3.0 atm. If the new volume is 0.52 L, find the original volume.

• 0.52 L
• 1.6 L

• 0.17 L

• 1.0 L

Which container will have a lower pressure?

• left
• right
• they both have the same pressure
• I don't know

True or False: Gases can be compressed. 

• True
• False

A sample of hydrogen at 1.50 atm had its pressure decreased to 0.500 atm producing a new volume of 750 L. What was its original volume?

• 245 L

• 345 L

• 123 L

• 250 L

A sample of carbon dioxide occupies a volume of 3.50 liters at 125 torr pressure. What pressure would the gas exert if the volume was decreased to 2.00 liters?

• 219 torr

• 222 torr

• 567 torr

• 654 torr

A 2.0 liter container of nitrogen had a pressure of 3.2 atm. What volume would be necessary to decrease the pressure to 1.0 atm?

• 7.2 L

• 5.0 L

• 6.4 L

If I have 5.6 liters of gas in a piston at a pressure of 1.5 atm and compress the gas until its volume is 4.8 L, what will the new pressure inside the piston be?

• 6.3 atm

• 2.4 atm

• 1.8 atm

• 8.6 atm

I have added 15 L of air to a balloon at sea level (1.0 atm). If I take the balloon with me to Denver, where the air pressure is 0.85 atm, what will the new volume of the balloon be?

• 24 L

• 18 L

• 32 L

• 15 L
