Five hundred joules of heat are added to a closed system. The initial internal energy of the system is 87 J, and the final internal energy is 134 J. How much work is being done by the system? 221 J 279 J 366 J 453 J

work done is 453 joules

Explanation:

given data

heat added = 500 J

initial internal energy = 87 J

final internal energy = 134 J

to find out

work done

solution

we know work done formula that is

work done = added heat energy - change in internal energy ... 1

so here

change in internal energy = final - initial energy

change in internal energy = 134 - 87

change in internal energy = 47 J

so from equation 1

work done = 500 - 47

work done = 453 J

so work done is 453 joules
