Question

A gas‑filled weather balloon has a volume of 59.0L at ground level, where the pressure is 769mmHg and the temperature is 21.7.After being released, the balloon rises to an altitude where the temperature is -4.44 and the pressure is 0.0635 atm. What is the weather balloon's volume at the higher altitude?

Answer 1

Use combined gas law and convert celsius to kelvin and use common pressure units.

I convert mmHg to atm: use unit factor 760 mmHg = 1 atm.

P1V1/T1 = P2V2/T2

Solve for V2 = T2P1V1/P2

V2 = 268.56 K ( 1.01184 atm) ( 59.0 L) / .0635 atm

V2 = 252,483 liters
