The latent heat of melting is 80 calories for 1 gram of ice. if 1 gram of ice absorbs 60 calories what do i get?
Eva8 [605]
Latent heat of melting is the energy that a solid absorbs to change its phase as its liquid. During this process, since all energy is used to change the phase, the temperature is constant.

Here the latent energy of melting for 1 g of ice is 80 calories and that 1 g of ice only absorbed 60 calories. hence the phase is not changed because it requires more 20 calories to melt.

Hence 1 g of ice remains as its solid phase (ice).
