Choose the right answer from the following

The system _____ energy while going from solid to the liquid state.

  1. releases
  2. absorbs
  3. absorbs and releases
  4. transforms

Answer: 2. absorbs

Explanation:

The system absorbs energy while going from solid to the liquid state. This absorbed energy would facilitate the molecules to overcome the force of attraction holding them together, enabling them to slip out of the fixed position that they held as a solid. The process in which a solid changes to liquid is called melting. The melting point is the temperature at which a solid changes to a liquid.
