If the energy of a system changes because of a temperature difference, we say there has been a flow of heat. Adiabatic and polytropic are two thermodynamic processes related to heat transfer in systems. Adiabatic. Adiabatic change is the one in which no heat is transferred into or out of the system. Heat transfer can be mainly stopped by two ways.
An adiabatic process can be either reversible or irreversible. In the case of the reversible adiabatic process, the entropy of the system remains constant. A reversible adiabatic process is therefore called isoentropic. On a phase diagram of the system it is represented by an adiabatic curve or by an isoentropic curve. In an irreversible adiabatic process the entropy increases.
