The 2nd law of thermodynamics states that for any isolated system, energy transfers will occur in a way that
increases entropy over time. Which
situation below is an example of the 2nd law in action
? (assume all situations
are isolated systems)
A. If gases A and B are the same temperature as gas C, they are the same temperature as each other.
B. A puddle of water evaporates into water vapor, even when it's cold.
C. A heat engine is given 100 Joules of heat energy, and performs 100 Joules of work to move a piston.
D. A substance at absolute zero has no energy, and molecular motion stops.
