Question

How much energy is transferred when 1 gram of ice water freezes to ice at 0 degrees celcius?

Answer 1

The definition of latent heat of freezing of water is,

The amount of heat energy released when 1 gram of ice water (0°C) change to 1 gram of Solid ice at 0°C.

We know latent heat of freezing of water is = – 80 Cal/gram

(-ve sign for energy release)

Hence 80 Calories of energy is transferred when 1 gram of ice water freezes to ice at 0 degrees celcius
