Question

Which of the following statements is incorrect?

• A. For an isothermal process, dT = 0.
  Where, T is the temperature of the system.
• B. For an adiabatic process, dW = 0,
  where, W is the work done in the process
• C. For an isobaric process, dP = 0.
  Where. P is the pressure of the system.
• D. For an Isochoric process, dV = 0.
  Where, V is the volume of the system.

Answer 1

The correct option is B For an adiabatic process, dW = 0,

where, W is the work done in the process
The thermodynamic process in which the temperature remains constant throughout is called as an isothermal process.
For an isothermal process, dT = 0.

The thermodynamic process in which the heat exchange between the system and the surrounding is not possible is called an adiabatic process.
For an adiabatic process, dQ = 0.

The thermodynamic process occuring at constant pressure is called isobaric process.
For an isobaric process, dP = 0.

The thermodynamic process occuring at constant volume is called isochoric process.
For an isochoric process, dV = 0.
