Question

A system absorb 600J of heat and work equivalent to 300J on its surroundings. The change in internal energy
is :
(A) 300J
(B) 400 J
(C) 500 J
(D) 600 j​

Answer 1

Answer:

Correct Answer is: (1) 300 J

Explanation:

  We know that ΔE = Q + W = 600 + (-300) = 300 J W= – 300, because the work done by the system.
