Question

A balloon is filled with helium gas at 23 degrees C. The balloon expands until the pressure is equal to the atmospheric pressure of 755 toor. The balloon rises to an altitude of 6000 feet where the pressure is 550 toor and the temperature is 5 degrees C. Calculate the percent increase in volume of the balloon as it ascends to 6000 feet?

Answer 1

Use (P1V1/T1) = P2V2/T2) and calculate the new volume at 6000 ft.
Then [(V2-V1)/V1]*100 = ??
