Define the latent heat of fusion. Why does the temperature remain constant during the melting of ice?
(N/A) Latent heat of fusion is the amount of energy required to change $1 \, kg$ of a solid into a liquid at its melting point.
During the process of melting ice,the heat supplied is used up in changing the state of the substance by overcoming the forces of attraction between the particles. Since this energy is consumed to break the intermolecular bonds rather than increasing the kinetic energy of the particles,the temperature does not rise and remains constant.
