Ideal Gas Law Math

A balloon with a volume of 5.3 L is taken from an indoor temperature of 24ºC to the outdoors. The volume of the balloon outside is 4.9 L. What happened to the Celsius temperature outside? PV=nRT

• Temperature increase

• Temperature decreases

The volume of a gas at 99.0kPa is 300mL. If the pressure is increased to 188kPa, what will happen to the volume? Increase or Decrease

• volume increases

• volume decreases

Determine the Celsius temperature of 2.49 moles of gas contained in a 1.00-L vessel at a pressure of 143 kPa. Solve for T and then change you answer to Celcius
