The gas in a perfectly insulated but there is work done on the flexible container at a rate of - $13 \mathrm {~W} .$ At what rate is the internal (thermal)energy of the gas changing?

Question

Quizplus · Accepted Answer

In a perfectly insulated system, no heat can be transferred in or out of the system. Therefore, the rate of change of internal energy is equal to the work done on the system. Since work is done on the system at a rate of -13 W, the internal energy of the gas is increasing at a rate of -13 W.

The Gas in a Perfectly Insulated but There Is Work 13 W.13 \mathrm {~W} .13 W.

The Gas in a Perfectly Insulated but There Is Work $13 \mathrm {~W} .$
