A beaker of water sits in the sun until it reaches an equilibrium temperature of 30°C. The beaker is made of 100 g of aluminum and contains 180 g of water. In an attempt to cool this system, a small block of ice at 0°C is added to the water.   a. Determine the exact mass of ice needed to melt (giving up its latent heat of fusion) and bring the water and beaker temperature down to 0°C. b. If the ice block has a mass of 100 g, determine the final temperature of the system. If it turns out that Tf = 0°C, determine how much ice remains unmelted.

Work and Heat Transfer

It is generally related to thermal engineering which tells about the use, creation, conversion and transfer of heat energy between the systems. It is also considered that to transfer heat from one source to another, transfer of masses is also required. There are various mechanisms by which, transfer of heat takes place i.e. thermal conduction, convection, radiation or by change of phase. All these mechanisms have their own specific features which sometimes occur simultaneously within the same system.
