A 15 liter rigid bottle contains 15 kg of the refrigerant R-134A and it is at a temperature of 20°C. It is left in a hot car and reaches a temperature of 65°C. Determine the initial and final pressures. Is there any possibility of the bottle failing due to excessive pressure? (You can make this determination if it is a subcooled liquid.)

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.
