Thermodynamic property, process and cycle

Thermodynamic property A thermodynamic property is a state variable whose value defines a state of the system for e.g. pressure, temperature, and volume. Thermodynamic properties are macroscopic in nature. When these values are constant, the system is said to be in a definite state. Thermodynamic properties are generally divided into…

Irreversibility of a thermodynamic process

To understand Irreversibility of a thermodynamic process first we have to understand what is reversibility. If in the end of a process both the systems and surroundings get restored to their original condition, the process is called reversible process. Similarly, if the system and surrounding are not restored to their original…

Thermodynamic equilibrium [Mechanical, Chemical & Thermal]

Thermodynamic Equilibrium A system is said to be in thermodynamic equilibrium, if no change in any macroscopic property (like pressure, volume and temperature) is observed when the system is isolated from the surroundings. A system which is isolated from its surroundings, automatically reaches equilibrium condition and cannot depart from it…
