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
The Second Law of Thermodynamics. The second law of thermodynamics says that the entropy of any isolated system always increases. Isolated systems spontaneously evolve towards thermal equilibriumâthe state of maximum entropy of the system. More simply put: the entropy of the universe (the ultimate isolated system) only increases and never decreases.
