Question

A weather balloon is inflated to a volume of 26.5Lat a pressure of 754mmHg and a temperature of 25.8?C. The balloon rises in the atmosphere to an altitude, where the pressure is 400mmHg and the temperature is -13.7?C.

Part A

Assuming the balloon can freely expand, calculate the volume of the balloon at this altitude.

A weather balloon is inflated to a volume of 26.5Lat a pressure of 754mmHg and a temperature of 25.8?C. The balloon rises in the atmosphere to an altitude, where the pressure is 400mmHg and the temperature is -13.7?C.

Part A

Assuming the balloon can freely expand, calculate the volume of the balloon at this altitude.

V2 = L  

Explanation / Answer

A/C to gas law

P1V1/T1= P2V2/T2

V2= P1V1T2 / P2T1= 754x26.5x259.3/400x298.8 = 19981x259.3/119520

V2=5181073.3/119520=43.35L
