For the problem below, the value for the final pressure is (a)   .
A gas with a volume of 4.0 L at 90.0 kPa expands until the pressure drops to 20.0 kPa. What is its new volume if the temperature doesn’t change?

• 4.0 L
• 20.0 kPa

On the sidelines at the game, a container filled with oxygen for the players has a volume of 0.03 L and a pressure of 4.00 atm. If the pressure of the oxygen gas is reduced to 2.71 atm and the temperature is kept constant, what is the new volume of the oxygen gas?

• 0.32 L
• 361 L
• 0.9 L
• 0.04 L

For a teammate’s birthday party, Martellus Bennett needs to buy a helium tank to fill up all of the balloons. If the helium must be compressed from an original volume of 27.0 L at 14.7 psi, down to a volume of 3.00 L, the final pressure of the helium would be (a)   .

• 132.3 psi
• 1.63 psi
• 5.51 psi
• 132.3 L
