Answer :

Final answer:

Ice melting is an endothermic process and involves energy absorption to transition from solid to liquid. Various phase changes have specific heat flow characteristics.


Explanation:

Ice melting to become liquid is an endothermic process. Energy is absorbed from the surroundings to break the bonds and transition the solid ice to liquid water.

Examples of other phase changes:

  1. Water boiling: Endothermic.
  2. Ice forming on a pond: Exothermic.
  3. Water vapor condensing: Exothermic.
  4. Gold melting: Endothermic.

In exothermic processes, heat is released to the surroundings, while in endothermic processes, heat is absorbed from the surroundings.
