Question

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 KE of helium atoms is (A) halved (B) unchanged (C) doubled (D) increased by factor √2

Tardigrade Admin · Accepted Answer

Kinetic energy propto Temperature. Hence if temperature is doubled, kinetic energy will also be doubled.

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

halved

unchanged

doubled

increased by factor $2$

Kinetic energy $\propto$ Temperature. Hence if temperature is doubled, kinetic energy will also be doubled.
