Question

Please help with A and B:

Part A

A sample of gas in a balloon has an initial temperature of 2 C and a volume of 1050 L . If the temperature changes to 63 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 = 2 C , V1= 1050 L ) to a volume of 2100 L ? Assume no change in pressure or the amount of gas in the balloon.

Express your answer with the appropriate units.

Explanation / Answer

A) V1/T1 = V2 /T2 as pressure is constant

T1 = 20C = 275 K , V1 = 1050 L

T 2= 630 C = 336 K

V2 = (V1T2 /T1)

V2 = (1050 x 336 / 275)

V2 = 1282.9 L

B) V1 /T1 = V2/T2

V1 = 1050 L , T1 = 20C = 275 K

V2 = 2100 L T2 = ?

T2 = (V2T1 / V1)

T2 = (2100 x 275 / 1050)

T2 = 550 K = 277 0C
