Helium gas is filled in a closed vessel ...

Helium gas is filled in a closed vessel whose coefficient of thermal expansion is negligible. When it is heated from 300 K to 600 K, then find the average kinetic energy of helium atoms.

Text Solution

Verified by Experts

The K.E. Becomes double, because average K.E. Per molecule of a gas is directly proportional to temperature in Kelvin.
