The energy required to heat water from 0°C to 100°C is less than the energy
needed to transform ice to water at 0°C.

Question

Quizplus · Accepted Answer

The energy required to heat water from 0°C to 100°C (specific heat capacity of water is about 4.18 J/g°C) is generally less than the energy needed to transform ice to water at 0°C, which involves the latent heat of fusion (about 334 J/g). Heating water involves raising its temperature, while transforming ice to water requires breaking molecular bonds, which consumes more energy.
