In which of the following processes the internal energy of system remain constant?

Options

  1. AIsobaric Process
  2. BIsochoric Process
  3. CIsothermal Process
  4. DAdiabatic Process

Correct answer

C. Isothermal Process

Step-by-step solution

The internal energy of an ideal gas is a function of its temperature only, given by U = f 2 n R T . For the internal energy to remain constant, the change in temperature must be zero ( T = 0 ). A process in which the temperature of the system remains constant is known as an isothermal process. Therefore, the internal energy of the system remains constant in an isothermal process. Answer: Isothermal Process
