A sealed container with negiligible coefficient of volumetric expansion contains helium (a monatomic gas). When it is heated from 300 K to 600 K, the average KE of helium atoms is

A

Halved

B

Unchanged

C

Doubled

D

Increased by factor `sqrt2`

Text Solution

Verified by Experts

The correct Answer is:
C
Kinetic energy `prop` Temperature
As `T to` doubles, `KE to ` also doubles.
