Sara Zannab on Nearpeer MDCAT Common Room
السلام عليكم ورحمة الله وبركاته Incorrect option is marked in this physics thermodynamics question? According to chatGPT and nearpeer AI as well, Answer should be A. work is done ON the system, so W is -ve: Q= U - W ------> U= Q + W (option A)

Q=u+w so finding u so move w toward left side

wouldn't it be Q= U-W. work would be -ve bcz it's done ON the system right? then moving W to other side, you get U= Q = W ?
