During a process, system absorbs 710 ~J of heat and increases the internal energy by 460 ~J . What is the work performed by system?
Options
- A-250 J
- B-1170 J
- C-710 J
- D-460 J
Correct answer
A. -250 J
Step-by-step solution
aligned & q =+710 ~J & U =460 ~J aligned From Ist law of thermodynamics, aligned & U = q + w & 460=710+ w & w =460-710 & =-250 ~J aligned
