Concept

Problem: What are the implications of the first law of thermodynamics?a. The first law has many implications, the most important of which is that you will always be losing energy. Energy is always being destroyed in the universe and is gone forever when used up.b. The first law has many implications, the most important of which is that energy is only ever created by work. In order to get energy, an equal amount of work must always be done.c. The first law has many implications, the most important of which is that you can always create more energy. Energy is always being created in the universe and can be supplied when needed.d. The first law has many implications, the most important of which is that with energy you do not get something for nothing. The best we can do with energy is break even — there is no free lunch.
