Question

If a small child were to release a balloon into the atmosphere, what would happen to the size of the balloon as it makes it way higher in the sky?
A) The balloon would become smaller because the pressure of the surrounding air would crush it.
B) The balloon would become smaller because the air molecules inside the balloon would get closer together.
C) The balloon would become larger because the air molecules on the inside of the balloon would expand.
D) The balloon would stay the same because the pressure inside the balloon is equal to the pressure of the atmosphere.

Answer 1

Answer: The correct answer is Option C.

Explanation:

As we move higher in the sky, the atmospheric pressure decreases. The relationship of pressure with volume is given by Boyle's Law.

This law states that the pressure of the gas is inversely proportional to the volume of the gas at constant temperature.

Mathematically,

$P\propto \frac{1}{V}$

where,

P is the pressure of the gas.

V is the volume of the gas.

If the pressure of the gas decreases, the volume increases and vice-versa.

As written above, the pressure at higher levels decreases, which results in the increase of volume. Hence, the balloon expands.

therefore, the correct answer is option C.
