What is "isothermal compression" and its definition in practise ? Please choose correct option. a. It is a compression during which temparature of the air is kept constant. Compression process should be done very slowly to allow any heat to transfer to the surrounding medium. b. It is the expansion of air in a motor, during which it is heated and given extra energy. c. It is the periodic compression and expansion of a gas in a compressor as to load and unload energy to it. d. It is the compression of air in a compressor, which is neither running too fast or too slow, suitable for practical purposes. e. It is the compression of air in a heat-insulated cylinder, but compression should be very slow.

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.
