A very flexible helium-filled balloon is released from the ground into the air at 20. ∘C

. The initial volume of the balloon is 5.00 L

, and the pressure is 760. mmHg

. The balloon ascends to an altitude of 20 km

, where the pressure is 76.0 mmHg

and the temperature is −

50. ∘C

. What is the new volume, V2

, of the balloon in liters, assuming it doesn't break or leak?

Please show how to work this using the equation:P1 V1 /T1 = P2 V2 / T2

T1 = 20. ∘C V1 = 5.00 L P1 = 760. mmHg The balloon ascends to an... View the full answer

(P1 * V1) / T1 = (P2 * V2 ) / T2 Where: T1  =  Initial temperature = 20 ∘ C = 20+273=293 K V1  = Initial volume... View the full answer
