Mechanisms of heat transfer

Heat transfer is an essential discipline in thermal engineering that deals with the transfer, conversion, usability, and creation of heat or thermal energy. Transfer of heat occurs through various mechanisms like conduction, convection, radiation, and change of phases. All these mechanisms have distinct characteristics, but these mechanisms can simultaneously occur in an identical system.

A piston-cylinder contains gas initially at 3500 kPaa with a volume of 0.03 m². The gas is compressed during a process where pV¹25= C to a pressure of 8500 kPaa. The heat transfer from the gas is 2.5 kJ. Determine the change in internal energy, neglecting changes in kinetic and potential energies. [Ans. 141.9 kJ]
* Your answer is incorrect. A piston-cylinder assembly contains 0.7 lb of propane. The propane expands from an initial state where p₁ = 60 lbf/in.² and T₁ = 70°F to a final state where p₂ = 10 lbf/in.² During the process, the pressure and specific volume are related by pv² = constant.
