Question

In a thermodynamic system, $\Delta U$ represents the increase in internal energy and $dW$ the work done by the system. Then correct statement is

• A. $\Delta U=dW$ is an isothermal process
• B. $\Delta U=-dW$ is an adiabatic process
• C. $\Delta U=-dW$ is an isothermal process
• D. $\Delta U=dW$ is an adiabatic process

Hint:

Physics Tip: Adiabatic process means no heat exchange: $Q=0$.

Answer 1

The Correct Option is B
