Replace the rubber boot and plug the light back in. Turn the lights on to check the right headlight. Turn them off. Repeat this procedure for the left headlight, but first remove the battery hold-down with a ratchet and socket, then remove the battery. Start by removing the negative cable first, then the positive.
Any device that violates the first or second law of thermodynamics is called a perpetual-motion machine. If the device violates the first law, it is a perpetual-motion machine of the first kind. If the device violates the second law, it is a perpetual-motion machine of the second kind. Reversible Processes
View full size image. The First Law of Thermodynamics states that heat is a form of energy, and thermodynamic processes are therefore subject to the principle of conservation of energy. This means that heat energy cannot be created or destroyed.The First Law says that the internal energy of a system has to be equal to the work that is being done on the system, plus or minus the heat that flows in or out of the system and any other work that is done on the system, said Saibal Mitra, a professor of physics at Missouri State University.
