Mathematical form of first law of thermodynamics is

Correct answer: B. delta E=q+w

  • A. delta H=qo
  • B. delta E=q+w
  • C. Delta E=q *v
  • D. all of these

Explanation

Explanation: The first law of thermodynamics states that the change in internal energy (Delta E) of a system equals the heat added to the system (q) plus the work done on the system (w).
