According to the first law of thermodynamics which of the following quantities represents the change in a state function?

Options

  1. Aqrevq_{\mathrm{rev}}
  2. Bqrev−Wrev q_{\mathrm{rev}}-W_{\text{rev }}
  3. CqrevWrev\frac{q_{\mathrm{rev}}}{W_{\mathrm{rev}}}
  4. Dqrev+Wrev q_{\mathrm{rev}}+W_{\text{rev }}

Correct answer

D. qrev+Wrev q_{\mathrm{rev}}+W_{\text{rev }}

Step-by-step solution

ΔE=qrev +Wrev ΔE\Delta E=q_{\text{rev }}+W_{\text{rev }} \Delta E is a state function.
