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

A. 400 J

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

true tan speed = ang vel x radius

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
