Question

A closed system’s internal energy changes by 178 J as a result of being heated with 658 J of energy. The energy used to do work by the system is J.

Answer 1

Answer:

480J

Explanation:

Using the formula:

Delta U = Q - W

Q:Heat (J)

Delta U: Changes in internal Energy (J)

W:Work (J)

We can plug in the give numbers, Q and W.

Delta U = 658J - 178J = 480J
