We know that the law of conservation of energy states that energy can not be created or destroyed. it only changes form. consider this energy transformation diagram. assume that the energy input in this case is chemical potential energy and the useful energy output is kinetic energy, specifically a small fan to keep you cool. the diagram also shows how to calculate the efficiency of the fan. if the law of conservation of energy holds true, explain why the efficiency of the fan is not 100%.
