In a thermodynamic system, ' W ' represents the work done by the system and ' U ' is the increase in internal energy. Which of the following statements is TRUE?

Options

  1. AIn an adiabatic process, U=-W
  2. BIn an isothermal process, U=W
  3. CIn an adiabatic process, U = W
  4. DIn an isothermal process, U =- n W

Correct answer

A. In an adiabatic process, U=-W

Step-by-step solution

Concept based. According to the first law of thermodynamics, Q = U + W In adiabatic process Q =0 So, U =- W
