Combined Gas Law Practice

A gas is heated from 263K to 298K. The volume is increased from 24.0L to 35.0L. If the original pressure was 101.33 kPa, what is the new pressure?

• 78.7 kPa

• 167.2 kPa

• 129.7 kPa

• 61.8 kPa

A weather balloon has a volume of 105 L at 98.3 kPa when the temperature is 318 K. What is the volume at 293 K and 106.4 kPa?

• 89.4 L

• 0.32 L

• 93.8 L

• 3.13 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?

• 1.8 atm

• 3.27 atm

• 1.8 L

• 3.27 atm

A gas is heated from 263K to 298K. The volume is increased from 24.0L to 35.0L. If the original pressure was 1.00 atm, what is the new pressure?

• 0.78 atm

• 1.65 atm

• 1.28 atm

• 0.61 atm

If 10L of Oxygen at 273K and 1 atm is compressed to a 7L container at 250K, what is the new pressure?

• 6.0 atm

• 9.16 atm

• 0.76 atm

• 1.31 atm

According to the Combined Gas Law, if the pressure exerted on a gas is tripled, what will happen to the volume and temperature?

• Volume is 1/3 and temperature is tripled

• Volume is 1/3 and temperature is 1/3

• Volume is tripled and temperature is 1/3

• Volume is tripled and temperature is tripled

A gas is at a pressure of 12 atm, a volume of 23 L, and a temperature of 200K. If the pressure is raised to 14 atm, and the temperature is increased to 300K. What is the new volume of the gas?

• P1V1T2 / P2T1

• P2V2T1 /P1V1

• P1V1T2 / P2V2

• P2V2T1 /V1T2
