Latent Heat of Fusion for Water . Keep all the masses in "grams " and temperatures in Celsius , Select ice (M icc ) from the "Solids" at 0 ^ 0 * C and then from "Liquids" (M_{w}) water with temperature T_{w} around 30 ^ 0 * C 2. Heat lost by the warm water is absorbed by the ice that melts and warms up. Notice the final temperature of water (T_{f}) 3. Calculate the latent heat of fusion for water, L_{f} using the following equation Q gaincd =IQ lost I. Specific heat of water is mathcal f yy =4.184 J/g C. I M ice L f +M ice^ * C w *(T f^ - 0)=M w * c w *(T w -T f )
