Pure water under the atmospheric pressure of 100,000 Pa is converted to steam at a temperature of 100 0C. Assuming that the chemical potential of water in the solution does not change much with pressure, work out the pressure at which the water in the salt solution will boil, at 100 0C.  You may take steam as being an ideal gas.

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.
