Answer #1

Energy us defined as capacity of doing the work.

Work is transferring an amount of energy through a force covering a particular distance in a particular direction.

Work is a systematic form of energy whereas energy is a discrete form.

W​​​​​​ is directly proportional to energy.

For phase change heat required is known as latent heat phase change take place at constant temperature so if ice is coverted into water then it Absorbs significant amount of heat but temperature remains the same (Melting Point)

So it's defined as hidden heat which is absorbed or radiated by the system during phase change.
