Is the application of latent heat of fusion applicable only to ice i.e.when ice melts but its temperature remains uniform

Open in App

Solution

No, it is not so. Latent heat of fusion is the heat required to change 1 kg of a solid substance into liquid state at the melting point of the substance.
