In an adiabatic process, which of the following statements is true?

Options

  1. AThe molar heat capacity is infinite
  2. BWork done by the gas equals the increase in internal energy
  3. CThe molar heat capacity is zero
  4. DThe internal energy of the gas decreases as the temperature increases

Correct answer

C. The molar heat capacity is zero

Step-by-step solution

For adiabatic process, dQ =0 Molar heat capacity =0 dQ =0 dU =- dW Also dU = f 2 nRdT Only option (3) is correct.
