For the engineers, the internal energy is the … Webw= -Pext (delta V). You need the negative in front because when work is done "on the system" (which is positive), delta V (Vfinal-Vinitial) is negative (the ballon is compressed). So the two negatives make the whole term for work positive. Side note: remember that external pressure (Pext) is considered constant.

WebSep 25, 2016 · 1. In very simple terms, when considering work you're talking about the energetic interactions within the system. You'll notice that, when an expansion takes place, Δ V has a positive sign as the final volume is greater than the initial volume. With the outer minus sign, the whole value adopts becomes negative.
