MP Board Book for Class 11th Physics Chapter 12- Thermodynamics

In this we will discuss the class 11th MP board physics chapter 12- thermodynamics. Some important definitions are being discussed.

Thermodynamics is to study the relationship between the four that is heat, work, temperature and energy. Equilibrium in mechanics means that the net external force.
According to Zeroth law of thermodynamics states that if two bodies are in thermal equilibrium with some other third body then all three are also in the same equilibrium.
It is also considered as an energy transformation and it is always related to matter.
First law of thermodynamics- It states that during an interaction it can be changed from one form to another form but the total remains constant as always.
Second law of thermodynamics- Energy has quality as well as quantity, actual process starts when the energy’s quality and quantity decreases.
Adiabatic process- The system is insulated from the surroundings and heat absorbed and released in zero.
Isochoric process- In this process, V is constant, no work is done on or by the gas.
Isobaric process- This process always takes place in a constant way.
Cyclic Process- In this process, the system returns to the initial stage.
Heat Engines- It is a device which is made to undergo a cyclic process which in the end results in a conversation of heat energy.
Carnot engine- Carnot engine is a reversible engine operating between two temperatures.
