Question

Part A: A sample of gas in a balloon has an initial temperature of 12 C and a volume of 2000 L . If the temperature changes to 84 C , and there is no change of pressure or amount of gas, what is the new volume, V2, of the gas? Express the volume numerically in liters.

Part B:

What Celsius temperature, T2, is required to change the volume of the gas sample in Part A (T1 = 12 C , V1= 2000 L ) to a volume of 4000 L ? Assume no change in pressure or the amount of gas in the balloon. Express the temperature numerically in degrees Celsius.

Show all work, Thank you!

Explanation / Answer

Part A,

at constant - P,n

V1/T1 = V2/T2

2000 / 12 = v2/84

v2 = 14000 L

part B,

V1/T1 = V2/T2

2000 / 12 = 4000/T2

T2 = 24 C
