Question

Part A

A sample of gas in a balloon has an initial temperature of 42 C and a volume of 1.87×103 L . If the temperature changes to 73 C , and there is no change of pressure or amount of gas, what is the new volume, V2, of the gas?

Express your answer with the appropriate units.

Part B

What Celsius temperature, T2, is required to change the volume of the gas sample in Part A (T1 = 42 C , V1= 1.87×103 L ) to a volume of 3.74×103 L ? Assume no change in pressure or the amount of gas in the balloon.

Express your answer with the appropriate units.

Explanation / Answer

part A

V1/T1 = V2/T2

(1.87*10^3)/(315.15) = (v2/346.15)

V2 = 2.053*10^3 L

part B

(1.87*10^3)/(315.15) = (3.74*10^3/T2)

T2 = 630.3 k

     = 357.15 C
