Question

If 400 joules of heat are added to a gas in an isochoric process, what is the

change in its internal energy?
O A. 400 J
O B.-400 J
O C. 100 J
OD. 200​

Answer 1

i’m pretty sure it’s A. 400 J

Answer 2

A. 400 J

Step-by-step explanation:

Because the process is isochoric, no volume change, so no work, so none of the energy is lost or converted. In other words, the system will gain and hold onto all of the J of heat put into it, which was 400J
