1. A sample of gas in a balloon has an initial temperature of 27 ∘C and a volume of 1.85×103 L . If the temperature changes to 82 ∘C , and there is no change of pressure or amount of gas, what is the new volume, V2 , of the gas?

2. What Celsius temperature, T2 , is required to change the volume of the gas sample in Part A ( T1 = 27 ∘C , V1 = 1.85×103 L ) to a volume of 3.70×103 L ? Assume no change in pressure or the amount of gas in the balloon.
