Chen explained that heat engines illustrate only the second law of thermodynamics because they involve the flow of thermal energy from hot to cool areas. His friend Mia disagreed and explained that these engines illustrate only the first law of thermodynamics because they are sometimes 100 percent efficient if they conserve enough energy.

Which statement best explains who is incorrect?

a. Chen is incorrect because heat engines illustrate only the first law of thermodynamics.

b. Chen is incorrect because in heat engines thermal energy flows from cool to warm areas.

c. Mia is incorrect because heat engines illustrate only the second law of thermodynamics.

d. Mia is incorrect because machines and engines can never be 100 percent efficient.
