The increase in internal energy of a system is equal to the work done on the system. Which process does the system undergo?

View answer and explanation

Correct option: B

Adiabatic

Option B is correct because if the increase in internal energy of a system is equal to the work done on the system (ΔU = W), and from the first law of thermodynamics ΔU = Q - W, then Q = 0, which defines an adiabatic process.
