Reading Quiz Question In a textbook, an illustration like that in the figure is used to represent a heat engine. If this is to represent your car, what parts of your car correspond to the parts of the diagram?

Reading Quiz Question Give a common example of a natural process that involves an increase in entropy. Be sure to account for all parts of the system under consideration.

Reading Quiz Question (Note: Evolution is frequently a hot-button topic. Your personal beliefs regarding the theory should not affect the answer to the question.) The theory of evolution posits that humans evolved from simpler organisms. Does this violate the second law of thermodynamics? Yes No Hard to define “disorder”

Lab Complete and measure the efficiency of a thermodynamic cycle.
