A liquid when kept inside a thermally insulated closed vessel at 25^ C was mechanically stirred from outside. What will be the correct option for the following thermodynamic parameters ?

Options

  1. AU 0, q =0, w 0
  2. BU =0, q =0, w =0
  3. CU 0, q =0, w 0
  4. DU =0, q 0, w 0

Correct answer

C. U 0, q =0, w 0

Step-by-step solution

Thermally insulated q=0 from I ^ st law aligned & U = q + w & U = w & w >0, U >0 aligned
