1.	Which among the following is the name of the thermodynamic system in which the temperature changes without supplying heat?1. Isothermal process2. Adiabatic process3. Isochoric process4. Quasi-static process
Answer» The correct answer is Adiabatic process. Adiabatic process It is a thermodynamic process in which there is no exchange of heat from the system to its surrounding neither during expansion nor during compression, yet the temperature may change. For the adiabatic process to occur, the system must be perfectly insulated from the surrounding. A reversible adiabatic process is called isentropic. Isothermal process It is a thermodynamic process in which the temperature of a system remains constant. The thermal equilibrium is maintained because the heat transfer is very slow. The work done in this process is due to the change of net heat content of the system. Isochoric process It is a thermodynamic process which takes place at constant volume. In such a process, the work done is zero. The volume of the gas remains constant. Quasi-static process It refers to an idealized process where the change in state is made infinitesimally slowly, such that at each instant, the system can be assumed to be at thermodynamic equilibrium with itself and with the environment.

Answer»

The correct answer is Adiabatic process.

Adiabatic process
- It is a thermodynamic process in which there is no exchange of heat from the system to its surrounding neither during expansion nor during compression, yet the temperature may change.
- For the adiabatic process to occur, the system must be perfectly insulated from the surrounding.
- A reversible adiabatic process is called isentropic.
Isothermal process
- It is a thermodynamic process in which the temperature of a system remains constant.
- The thermal equilibrium is maintained because the heat transfer is very slow.
- The work done in this process is due to the change of net heat content of the system.
Isochoric process
- It is a thermodynamic process which takes place at constant volume.
- In such a process, the work done is zero. The volume of the gas remains constant.
Quasi-static process
- It refers to an idealized process where the change in state is made infinitesimally slowly, such that at each instant, the system can be assumed to be at thermodynamic equilibrium with itself and with the environment.
