WebThe maximum amount of work one can attain from heat is given by the Carnot efficiency. Heat is the energy associated with the random motion of particles, while work is the energy of ordered motion in one direction. Therefore heat is "low-quality" energy and work is "high-quality" energy, and this supports the entropy statement of the Second Law. portlethen home bargainsWeb15 de mar. de 2024 · Generating electricity from the Geothermal (Earth’s heat).
