What is the final temperature of the water and the glass in C (specific heat of water =1.00 cal/g C, specific heat of glass =0.200 cal/gm C)? 14. The latent heat of fusion to melt lead at 327.0C is 22.9 kJ/kg and the specific heat of lead is 0.130 kJ/kgC. What is the energy needed to melt 100 grams of lead starting at 0C?
