If a gas expands at contant temperature,...

If a gas expands at contant temperature, it indicates that :

A

kinetic energy of molecules decreases

B

pressure of the gas increases

C

kinetic energy of molecules remains the same

D

number of the molecules of gas increases

Text Solution

Verified by Experts

The correct Answer is:
C
`KE=(3)/(2)RT` (for one mole of a gas)
As, the kinetic energy of a gaseous molecule depends only on temperature, thus at constant temperature, the kinetic energy of the molecules remains the same.
