A 3.87kg lead billet is to be melted for a casting operation. Lead has a melting point of 328°C, a specific heat capacity of 128 J/(kg·K), and latent heat of fusion of23,200 J/kg. Calculate the amount of heat required to heat the lead from a starting temperature of 22.4°C to its melting point of 328°C. Calculate the amount of heat needed to melt the lead brick once it reaches 328°C.
