Question

Experiment to deterimine the specific heat fusion

Answer 1

Heat” represents the thermal energy of molecules in a substance. Water freezes at 0 degrees Celsius. But the temperature of an ice cube can fall well below that. When an ice cube is removed from a freezer, the cube's temperature increases as it absorbs heat from its surroundings. But once the ice cube reaches 0 C, it begins to melt and its temperature stays at 0 throughout the melting process, even though the ice cube continues to absorb heat. This occurs because the thermal energy absorbed by the ice cube is consumed by water molecules separating from each other during melting.

The amount of heat absorbed by a solid during its melting phase is known as the latent heat of fusion and is measured via calorimetry.
