[b]1. Given the set-up in Figure 1, how much work will be done after part of the weight is removed, as shown in Figure 2, knowing only the height the piston rises?
[b]2. W=mC[P](T[2]-T[1])+mg(h[2]-h[1])
[b]3. W=mC[P](T[2]-T[1])+(m[2]-m[1])g(h[2]-h[1])
[b]1. Machine A and machine B are performing the same task. Machine A is causing twice the entropy change of machine B. Which would you rather use and why?
[b]3. I would choose Machine B. Lots of disorder = high entropy, while order = low entropy.
[b]1. A rigid container is filled with a mixture of three gases: A, B and C. the pressure gauge reads P[T]. The container is evacuated and fill with an amount of gas A equal to that in the original mixture. The gauge now reads P[A]. This process is repeated for gases B and C with the pressure...
