Bottom to top
Explanation:
- The ice melts from bottom to top
- Melting process starts the moment you take it out of the freezer.
- The air around the ice cube is warmer and the ice particles absorb heat energy from the warm air.
- It gives energy to the solid ice particles and enables them to move away from one another and starts melting.
- And when we keep the ice cube on a solid surface, it absorbs the heat of the surface and starts melting although the upper portion is only in contact with the air, hence it receives less energy.
