Vedclass · Answer

(B) According to the first law of thermodynamics, the change in internal energy $dU$ is given by $dU = dQ - dW$, where $dQ$ is the heat supplied to the system and $dW$ is the work done by the system.Given that the work done by the system is equal to the decrease in its internal energy, we have $dW = -dU$.Substituting this into the first law equation:$dU = dQ - (-dU)$$dU = dQ + dU$$dQ = 0$Since the heat exchange $dQ$ is zero, the process is an adiabatic process.

In a process, the work done by the system is equal to the decrease in its internal energy. The process that the system undergoes is
