Adiabatic Index
Adiabatic index is also known as adiabatic ratio, and adiabatic index is defined as the ratio specific heat at constant pressure to specific heat at constant volume.
So Adiabatic Index is given as
γ = Cp/Cv
where,
- γ is Adiabatic Index
- Cp is Specific Heat at Constant Pressure
- Cv is Specific Heat at Constant Volume
Note:
- In adiabatic process, heat exchange is zero but temperature change is not zero i.e. temperature of system changes in adiabatic process.
- Adiabatic expansion causes cooling up of system and adiabatic compression causes heating up of the system.
- In most of the times, an adiabatic change is a sudden change. During a sudden change the system does not find any time to exchange heat with its surrounding.
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.
