Which of the following processes exhibits, U = 0 ?

Options

  1. AAdiabatic process
  2. BIsothermal process
  3. CIsobaric process
  4. DIsochoric process

Correct answer

B. Isothermal process

Step-by-step solution

The internal energy of an ideal gas is a function of temperature only. The change in internal energy is given by U = n C_v T . In an isothermal process, the temperature of the system remains constant, which implies T = 0 . Substituting T = 0 yields U = 0 . Therefore, an isothermal process exhibits U = 0 . Answer: Isothermal process
