What is the net change in internal energy (ΔU) if the amount of work done (W) is the same as the amount of energy transferred in by heat (Q)?

ANSWER:

Zero

STEP-BY-STEP EXPLANATION:

Heat (Q) and work (W) are the two ways to add or remove energy from a system. The processes are very different, however, both can change the internal energy (ΔU) of a system.

It is given by the following equation:

[tex]\begin{gathered} \Delta U=Q-W \\ \\ \text{ So if they are the same:} \\ \\ Q=W \\ \\ \Delta U=Q-Q \\ \\ \Delta U=0 \end{gathered}[/tex]

The net change in internal energy (ΔU) is zero
