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
