U6.5 Gas law calculation

The gas in the container is at a pressure of 3.00 atm at 298 K.  What would be the pressure in the container at 325 K?

• P1/T1 = P2/T2
• P1V1 = P2V2
• V1/T1 = V2/T2
• PV = nRT

What is 50 ⁰C in Kelvin?

• 223 K

• 323 K

• 100 K

• 50 K

If a beach ball has a volume of 261 L at a temperature of 502 K, what will be the new temperature of the balloon if the volume decreases to 176 L and the pressure remain constant?

• 744 K

• 0.0030 K

• 339 K

• 512 K

• 1.00 L

Tom Brady enjoys balloon animals from the carnival. He just received a balloon giraffe that has an initial temperature of 39.0°C and a volume of 1.28 L. If Gronkowski plays a trick on Tom, and puts his balloon giraffe into the freezer, what would be the new volume of the balloon if the temperature drops down to 8.0°C?
(Don’t forget about what must be done to temperatures!)

• 1.42 L
• 6.85 x 10⁴ L
• 3.78 L
• 1.15 L
