Which of the following process is possible according to the first law of thermodynamics?

Options

  1. AW>0,Q<0\mathrm{W} > 0, \mathrm{Q}< 0 and dU=0\mathrm{dU}=0
  2. BW>0,Q<0\mathrm{W} > 0, \mathrm{Q}< 0 and dU>0\mathrm{dU} > 0
  3. CW>0,Q<0\quad \mathrm{W} > 0, \mathrm{Q}< 0 and dU<0\mathrm{dU}< 0
  4. DW<0,Q>0\mathrm{W}< 0, \mathrm{Q} > 0 and dU<0\mathrm{dU}< 0

Correct answer

C. W>0,Q<0\quad \mathrm{W} > 0, \mathrm{Q}< 0 and dU<0\mathrm{dU}< 0

Step-by-step solution
