a balloon inflated with helium gas at ground level is released. As it rises through a constant temperature atmosphere.
its pressuren reduces but volume remains constant
te product of pressure and volume remains constant
both pressure and volume increases
its pressure remains constant but the volume decreases
both pressure and volume remains constant

The correct answer is:
B) the product of pressure and volume remains constant
As the balloon rises through a constant temperature atmosphere:
1)The pressure decreases (due to lower air pressure at higher altitudes)
2)The volume increases (since the balloon expands as the surrounding pressure decreases)
This is an example of Boyle's Law, which states that at constant temperature, the product of pressure and volume remains constant:
P1V1 = P2V2
So, even though the pressure and volume change individually, their product remains constant.
