In a thermodynamic system, if there is no change in temperature and internal energy, then the process is called an
Correct answer: D. Isothermal process.
- A. Isobaric process.
- B. Adiabatic process.
- C. Isochoric process.
- D. Isothermal process.
Explanation
The correct answer is isothermal process. In an isothermal process, the temperature of the system remains constant. If there is no change in internal energy, it means that the work done by the system is balanced by the heat absorbed or released. This is characteristic of an isothermal process. An adiabatic process, on the other hand, involves no heat exchange, leading to changes in temperature and internal energy, making it incorrect in this context. Isobaric and isochoric processes are defined by constant pressure and volume, respectively, and do not inherently involve constant temperature and internal energy.

About Thermal Equilibrium and Heat
Thermal equilibrium means that bodies in contact have the same temperature and no net heat flows between them. The topic distinguishes heat from temperature, uses the zeroth law of thermodynamics, and covers heat transfer, specific heat capacity, thermal expansion and the conditions for reaching equilibrium.
