Question

Ice gets converted into liquid water by:

• A. Heat is absorbed.
• B. Heat is released.
• C. Temperature increases.
• D. Temperature decreases.

Answer 1

The correct option is B

Heat is released.

Ice being a solid comprise of very closely packed particles which possess very less kinetic energy. These particles have very high interparticle forces of attraction. On heating, the kinetic energy of the particles increases. ($0^{o}C$) is the melting point of ice, this is the temperature at which the particles gain a sufficient amount of energy to overcome the inter-particle force of attraction, move apart and get converted into the liquid state.
