The enthalpy H of a thermodynamic system is defined as H = U + PV where U, P and V are internal energy, pressure and volume of the systemLet is the heat absorbed in a constant pressure process (First law of thermodynamics) So, A constant pressure is mechanically reversible since if there are unbalanced mechanical …
Isothermal ProcessWhen a thermodynamic system undergoes a process under the condition that its temperature remains constant, then the process is said to be isothermal.Adiabatic ProcessWhen a thermodynamic system undergoes a process under the condition that no heat comes into or goes out of the system then process is said to be adiabatic.Isobaric ProcessWhen a thermodynamic …
