Question

Explain the different thermodynamic process
1. Isobaric process
2. Isochoric process
3. Adiabatic process​

Answer 1

Answer:

1. An Isobaric process is a thermodynamic process in which the pressure stays constant: ΔP = 0. The heat transferred to the system does work, but also changes the internal energy of the system. Using this convention, by the first law of thermodynamics, where W is work, U is internal energy, and Q is heat.
2. An isochoric process, also called a constant-volume process, an isovolumetric process, or an isometric process, is a thermodynamic process during which the volume of the closed system undergoing such a process remains constant.
3. An adiabatic process occurs without transferring heat or mass between a thermodynamic system and its surroundings. Unlike an isothermal process, an adiabatic process transfers energy to the surroundings only as work.

Answer 2

1. Isobaric process:- It is a process in which pressure of the system remains constant is known as isobaric process. temperature and volume of the system may change in this process.

Eg. All the reactions or processes taking place in open vessel like boiling of water in open vessel, burning of charcoal.

2. Isochoric process:- It is a process in which volume of the system remains constant is known as isochoric process.

Eg.1 All the reactions in closed vessel.

Eg.2 All the reactions occuring in bomb calorimeter are isochoric process.

3. Adiabatic process:- It is a process in which no energy exchange takes place and energy of the sytem remains constant is called adiabatic process. Adiabatic process occurs in isolated systems.

Eg. All processes taking place in isolated systems.
