A system does 200J200J of work and at the same time absorbs 150J150J of heat. The magnitude of the change in internal energy is ______JJ. (Nearest integer)

Correct answer

0

Step-by-step solution

w=−200J,q=+150:\DeltaU=q+ww = - 200J, q = + 150: \DeltaU = q + w

\DeltaU=150−200=−50J:\DeltaU = 150 - 200 = - 50J: magnitude =50J=∣\DeltaU∣= 50J = | \DeltaU |
