1. Consider a casting made by pouring 200 g of liquid aluminum initially at a temp 700 0C (Tp) into a mold made of plain carbon steel. The steel has a total mass of 3 kg and is initially at a temp of 20 0C. If the transfer of heat from the mold to the surrounding atmosphere is negligibly small, then heat transferred from the Al during solidification and subsequent cooling is absorbed by the mold. Assuming such a condition, estimate Tfinal of the mold and the casting.
