For isochoric process, the first law of thermodynamics can be expressed as

Options

  1. AU = Qv
  2. B- U = Q - P V
  3. C- U =- W
  4. DW =- Q

Correct answer

A. U = Qv

Step-by-step solution

For Isochoric process, Volume remains constant. aligned & V =0 & ~W =- P V =0 aligned First Law of thermodynamics, U = q + W At constant volume condition, ( W =0, q = q _ v ) U = q _ v Or U = Q _ V
