A solid is melted and allowed to cool and solidify again. The temperature is measured at equal intervals of time. The graph below shows the change of temperature with time. The part of the curve that is practically horizontal due to

Options

  1. Alatent heat given away by the liquid
  2. Bspecific heat given away by the liquid
  3. Cthermal capacity changes with time keeping temperature constant
  4. Dchange in density during transformation

Correct answer

A. latent heat given away by the liquid

Step-by-step solution

Latent heat is the energy absorbed or released at constant temperature per unit mass for change of state.
