Gas Laws Charles

What is the formula Charles' Law?

• V = T
• VT = VT
• T₁ / V_{1 =} T₂ / V₂
• V₁ / T₁ = V₂ / T₂

(Charles Law) There are 65 liters of helium in a balloon at 35 K. If the temperature of the balloon is increased to 40 K, what will the new volume of the balloon be?

• 40 L

• 70 L

• 74.3 L

• 75.9 L

(Charles Law) 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

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

Tom wants his balloon back to normal size so he decides to put it on a heating vent. If the balloon initially has a volume of 0.6 L and a temperature of 293 K, what will the volume of the balloon be when it heats up to a temperature of 176°C?

• 0.39 L
• 0.92 L
• 0.78 L
• 0.92 K

Edelman and Gronkowski want to play a game of beach volleyball. If the beach ball has a volume of  261 L at a temperature of 502 K, what will the temperature of the balloon be if the volume decreases to 176 L?

• 0.0030 K
• 339 K
• 512 K
