If a balloon is taken outside on a very cold day, what will occur?

Question

A.

The volume of the balloon will decrease.
B.

Gas will flow into the balloon.
C.

The volume of the balloon will increase.
D.

The pressure inside the balloon will increase.

Answer 1

The correct answer is:

A. The volume of the balloon will decrease.

This occurs because the gas inside the balloon cools down in the cold temperature, which reduces the kinetic energy of the gas particles. According to Charles's Law, the volume of a gas decreases as the temperature decreases, assuming pressure remains constant.
