$\Delta U = -\Delta W$ in an adiabatic process

(D) According to the first law of thermodynamics,the heat supplied to a system $(\Delta Q)$ is equal to the sum of the change in internal energy $(\Delta U)$ and the work done by the system $(\Delta W)$: $\Delta Q = \Delta U + \Delta W$ In an adiabatic process,there is no exchange of heat between the system and the surroundings,so $\Delta Q = 0$. Substituting this into the first law equation: $0 = \Delta U + \Delta W$ Therefore,$\Delta U = -\Delta W$.
