Tips on Understanding Charles’ Law

What happens to the volume of an inflated balloon when it is exposed to cold air?

a. the temperature inside the balloon rises.
b. the pressure inside the balloon rises.
c. the volume of the balloon decreases.
d. the volume of the balloon increases.

The correct answer would be C. The volume of the balloon will decrease.

Explanation:

As depicted in Charles’ Law, which states that volume and temperature are directly proportional to each other when the pressure of the gas is constant. When an inflated balloon is exposed to cold air, the volume of the balloon will decrease. This is because the gas pressure inside the balloon remains the same.

Charles’ Law can be represented by the equation V/T = K, where V is volume, T is temperature, and K is a constant pressure. Remembering this concept can help in understanding how the volume of a balloon changes when exposed to different temperatures.
