Question

Part A

A very flexible helium-filled balloon is released from the ground into the air at 20Celcius. The initial volume of the balloon is 5.00L, 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 Celcius What is the new volume, V2, of the balloon in liters, assuming it doesn't break or leak?

Express your answer with the appropriate units.

Part B

Consider 4.00L of a gas at 365 mmHg and 20. Celcius. If the container is compressed to 2.70L and the temperature is increased to 30.Celcius , what is the new pressure, P2, inside the container? Assume no change in the amount of gas inside the cylinder.

Express your answer with the appropriate units.

Explanation / Answer

since pv=constant

thus p1v1=p2v2

v2=p1v1/p2=760*5/76=50l

part b

p2=p1v1/v2=365*4/2.7=540.74 mm hg
