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

unchaged

C

doubled

D

increased by factor`sqrt2`

Text Solution

Verified by Experts

The correct Answer is:
C
When a sealed container with negligible confficient of volumetric expansion contains helium is heated , form 300K to 600K , the average kinetic energy of helium atoms is doubled.
