If a gas expands at constant temperature...

If a gas expands at constant temperature:

A

The pressure decreases

B

The kinetic energy of the molecules remains the same

C

The kinetic energy of the molecules decreases

D

The number of molecules of the gas increases

Text Solution

Verified by Experts

According to Boyle's law, when a gas is expanded at constant temperature, its pressure decreases. Kinetic energy is a function of temperature only, so it remains the same.
