Solution

The correct option is B Only potential energy decreases
potential energy increases with states solid-liquid-gas. Solids have least potential energy and gases have more. Ice has lesser potential energy than water.

Water when stored is potential and as a freely flowing has kinetic energy associated with it.
Hence water is converted into ice and maintained at $0^{o} C$ , which of the following statements is true for the molecules of the substance potential energy decreases.
