Q.
A sealed container with negligible coefficient of volumetric expansion contains helium (a monoatomic gas). When it is heated from $300\ K$ to $600\ K,$ the average K.E. of helium atoms is
A) Halved
B) Unchanged
C) Doubled
D) Increased by factor $\sqrt{2}$
Explanation
(c) Kinetic energy $\propto$ Temperature. Hence if temperature is doubles, kinetic energy will also be doubled
