Question

A helium weather balloon is inflated so that the pressure inside is at Earth's atmospheric pressure (approximately 101 kPa). If the balloon is then released on a planet whose thin atmosphere results in a pressure inside the balloon that is half that of Earth's atmospheric pressure, what will happen to the balloon's volume?

Answer 1

The volume of the balloon wil increase to the double of the initial volume.

Step-by-step explanation:

p2= p1/2

p1*v1= p2*v2

p1*v1= p1/2 * v2

p1*v1 / p1/2 = v2

2* v1 = v2
