We consider a thermodynamic system. If ΔU\Delta U represents the increase in its internal energy and WW the work done by the system, which of the following statements is true?
View answer and explanation
Correct option: A
ΔU=−W\Delta U = - W in an adiabatic process
Option A (ΔU=−W\Delta U = - W in an adiabatic process) is correct because in an adiabatic process, there is no heat exchange, so the change in internal energy is equal to the negative of the work done by the system.
