We have 39.5 g of a particular substance. Its specific heat in solid form is 0.8 J/(g K) and its specific heat in liquid form is 1.4 J/(g K); it's latent heat of melting is 170 J/g. Its initial temperature is 196 and its melting point is 223. We wish to raise its temperature to 297 (where it is a liquid). How much heat is required?
