Answer:
The properties of ice – melting and freezing are involved in its change during heating and cooling.
- Heating of ice leads to melting of ice. When ice is heated and temperature rises, thermal energy from heat is absorbed by the ice.
- At a certain point, the temperature remains constant and does not increase, and at this state, ice changes from its solid-state to liquid state at the melting point.
- The heat energy makes the ice particles to vibrate more rapidly and to disintegrate its form.
- When ice is cooled, the thermal energy is lost, the particles will slow down and come closer and the force of attraction increases.
- This makes crystals to be formed in the liquid which eventually solidifies to form ice at the freezing point.
