Two spheres, each 6 ft in diameter, are connected by a pipe in which there is a valve. Each sphere contains helium at temperature of 80°F. With the valve closed, one sphere contains 3.75 lb and the other 1.25 lb of helium. After the valve has been open long enough for equilibrium to obtain, what is the common pressure in the spheres if there is no loss or gain of energy.

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.
