Climbing up converts the kinetic energy of muscle movement to potential energy. Diving converts potential energy to kinetic energy. A diver has less potential energy in the water than on the platform. The Laws of Energy TransformaGon •  Thermodynamics is the study of energy transformaGons •  A closed system, such as that approximated by liquid in a thermos, is isolated from its surroundings •  In an open system, energy and maQer can be transferred between the system and its surroundings •  Organisms are open systems The First Law of Thermodynamics •  According to the first law of thermodynamics, the energy of the universe is constant: – Energy can be transferred and transformed, but it cannot be created or destroyed •  The first law is also called the principle of conservaGon of energy The Second Law of Thermodynamics •  During every energy transfer or transformaGon, some energy is unusable, and is oUen lost as heat •  According to the second law of thermodynamics: – Every energy transfer or transforma<on increases...
