Question

Kinetic energy of molecules in helium is __________[Large/very large] compared to the kinetic energy of molecules in water.

Open in App

Solution

Since helium is gas and in gases force of attraction is negligible, hence the energy is very high as compared to solids and liquids,
Therefore, Kinetic energy of molecules in helium is very large compared to the kinetic energy of molecules in water.
