Reversible Adiabatic Process

A reversible adiabatic process is when a system changes its state without exchanging heat with the surroundings, and the changes are reversible, meaning it can go back and forth without any energy loss as heat. This process occurs without any external influence and is characterized by a rapid, frictionless, and perfectly efficient transformation.

Example of Reversible Adiabatic Process is expansion of steam in steam turbines and gas in gas turbines.

Adiabatic Process

Adiabatic Process is a thermodynamic process in which there is no heat exchange between the system and the environment. It means the energy of the system remains unchanged with time. For Example, the water inside a thermo steel bottle that remains hot is one of the best real-life examples of the Adiabatic Process.

In this article, we will learn what the is Adiabatic Process, its definition, example, and equation to explain the process and its graphical representation. We will also solve some numerical based on the adiabatic process and see the previous year’s questions of competitive exams.

What is Adiabatic Process?

Adiabatic Process is a thermodynamic change in a system where no heat is exchanged with its surroundings. It is a quick and efficient transformation that happens without any heat coming in or going out. Adiabatic processes commonly occur in gases and are characterized by their swift nature, often taking place too rapidly for any significant change to happen....
