Question

How does ice gets converted into liquid water?

• A. Ice converts into liquid water by releasing heat.
• B. Ice converts into liquid water by absorbing heat.
• C. Ice converts into liquid water neither by absorbing nor by releasing heat.
• D. It is not possible to find.

Answer 1

The correct option is B

Ice converts into liquid water by absorbing heat.

Ice is a solid comprise of very closely packed molecules which possess less kinetic energy. On heating, the particles in ice gain kinetic energy, at the melting point of ice ($0^{\circ }C$), the particles gain sufficient amount of energy to overcome the inter-particle force of attraction and get converted into liquid form. At $0^{\circ }C$ energy supplied is used to overcome intermolecular forces and no kinetic energy is gained by particles.
