To do work in physics you must
WebbYou must have energy to accomplish work - it is like the "currency" for performing work. To do 100 joules of work, you must expend 100 joules of energy. Power. is the rate of doing work or the rate of using energy, which are numerically the same. If you do 100 joules of work in one second (using 100 joules of energy), the power is 100 watts. Index WebbBy conservation of energy, the work done per cycle is W = Q1 – Q2, and the net entropy change is To make W as large as possible, Q2 should be as small as possible relative to Q1. However, Q2 cannot be zero, because this would make Δ …
