Isothermal Process - Definition, Example, Formula, FAQs

Since, processes which occur at constant temperature are called isothermal processes. Process which occurs at constant magnitude of volume is called Isochoric. And, all the thermodynamic processes which occur at constant heat are called adiabatic processes, So, the correct option is (C) Heat.

The thermodynamics process in which the temperature of the whole system remains constant over a period of time is called isothermal process. So, the constant temperature of any system makes the process an isothermal process. For example, melting of ice at zero degree is such an example of an isothermal process.

In an isothermal process, the temperature of the system remains the same, so the change in temperature is always zero, and due to this the change in internal energy in an isothermal process is always zero, SO, the correct option is (D) zero.

In an isothermal process, the temperature of the whole system is always the same and as well as the change in internal energy in isothermal process of the system is always zero. So, the correct option is During isothermal process (A) Temperature remains same and (B) Change in internal energy is zero.

Temperature remains constant.

Internal energy of the gas unchanged
