If a gas expands at constant temperature...

If a gas expands at constant 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 molecule of gas increases.

Text Solution

Verified by Experts

The correct Answer is:
C
Kinetic energy , KE = `(3)/(2)` RT
`KE prop T`
Here , the temperature of gas remains constant , hence kinetic energy of molecules remains the same
