Question

What is an isothermal process ? Gives an example. Write the essential conditions for this process to take place.

Answer 1

Thermodynamics is a branch of science which deals with the change in the properties of system during any physical or chemical change. It mainly involves the change in energy from system to surrounding or vice-versa. When a system shows a change in energy then it undergoes the thermodynamic process. The change in energy is accompanied by change in some parameters like internal energy, pressure, volume, temperature.

There are various types of thermodynamic processes which are mostly occurring in practical cases. Each process is specific and unique with its properties and useful for determining the change in energy and the amount of work which is done for changing the energy of the system; for example, isobaric process, isothermal process, adiabatic process, and isochoric process. It is also possible to complete more than one process at a time; for example, when there is a change in volume and pressure then there is no change in temperature and no heat transfer takes place, this is the combination of adiabatic & isothermal thermodynamic process.
