CHAPTER(2) – Concepts of Thermodynamics

Thermodynamic process

Thermodynamic process:         It is the path or operation by which a system changes from one state to another state. 1. Isothermal process:          The temperature of the system remains constant during each step.        T = constant => dT = 0      Details: For such change system should be contained in a perfectly conducting container. Perfect …

Reversiable and Irreversiable process

Reversible Process:                    A thermodynamically reversible process is one in which all the changes occurring in any part of the process are exactly reversed when it is carried out in opposite direction. Characteristic of the reversible process: It has to be carried out in infinitesimal amount and hence require infinite time. Therefore changes in this process …
