Julian and Jimmy are playing basketball outside in 82°C weather. If they leave the ball outside and temperature drops down to 53°C, what will happen to the volume of the gas in the ball if the pressure remains constant?

• volume will remain the same

• volume will increase

• volume will decrease

• volume will double in size

There are 40 liters of helium in a balloon at 100 K. If the temperature of the balloon is increased to 200 K, what will the new volume of the balloon be?

• 80 L

• 45 L

• 54 L

• 45.33 L

A student inflates a balloon with helium then places it in the freezer. The student should expect

• the balloon's volume to increase

• the balloon's volume to decrease

• the balloon's moles to increase

• the balloon's moles to decrease

I have an unknown volume of gas held at a temperature of 200 K in a container with a pressure of 60.0 atm. If by increasing the temperature to 325 K and decreasing the pressure to 20.0 atm causes the volume of the gas to be 29 liters, how many liters of gas did I start with?

• 1.8 liters

• 67.2 liters

• 15.8 liters

• 5.9 liters

• none are correct

• 649 ml

• 386 ml

• none are correct

A certain sample of gas has a volume of 0.452 L measured at 87^oC and 0.620 atm. What is its volume at STP
