Heat equation for melting ice

WebThe heat needed to change the temperature of a given substance (with no change in phase) is: q = m × × c × × ΔT (see previous chapter on thermochemistry). The heat needed to induce a given change in phase is given by q = n × × ΔH. Using these equations with the appropriate values for specific heat of ice, water, and steam, and ...
