Question

How does ice (solid state) get converted into water (liquid state)?

• 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 molecules which possess less kinetic energy. Our target is to convert it into the liquid state in which particles are comparatively at a greater distance and will have higher kinetic energy. So, heat energy has to be supplied to ice so that the force of attraction between the particles break up and kinetic energy increases.
