Solution

The correct option is B False

Heat is absorbed by ice when it changes into water.

  • Melting or Fusion: The process due to which a solid change into a liquid state by absorbing heat energy is called melting or fusion.
  • The kinetic energy (K.E.) of solid particles increases by increasing the temperature.
  • The particles start vibrating with greater speed, due to an increase in kinetic energy.
  • The energy supplied by heat overcomes the force of attraction between the particles. Then, the particles leave their fixed positions and start to move freely, and thus solid changes into a liquid.
