The temperature of an enclosed gas at constant pressure changes from 200 K to 800 K. What happens to the volume of the gas? a The volume will decrease to one-half (1/2) of its original volume. b The volume will increase to 4 times its original volume. c The volume will decrease to one-fourth (1/4) of its original volume. d The volume will increase to 2 times its original volume. e The volume will stay the same.

According to Charles's Law, at constant pressure, the volume of a gas is directly proportional to its temperature. Therefore, as the temperature of the gas increases from 200 K to 800 K, the volume of the gas will increase.

The correct answer is:

d) The volume will increase to 2 times its original volume.
