Question

$dU+dW=0$ is valid for :

• A. adiabatic process
• B. isothermal process
• C. isobaric process
• D. isochoric process

Answer 1

The correct option is A adiabatic process

According to first law of thermodynamics we have $dQ=dU+dW$
For an adiabatic process, we know that $dQ=0$
Therefore we have $dU+dW=0$
