. A closed flask contains water in all its three states solid


liquid and vapour at 0 degree C. In this situation, the average kinetic energy of water molecules will be

(a) the greatest in all the three states

(b) the greatest in vapour state

(c) the greatest in the liquid state

(d) the greatest in the solid state.

 

Best Answer

Correct Option is : (b)

In the three states of matter, the maximum kinetic energy is possessed by the gaseous molecules, so water vapour state has maximum kinetic energy in this situation.
