We know that the law of conservation of energy states that energy can not be created or destroyed. It only changes form. Conside
r 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%. A) No machine is ever 100% efficient; some energy is not transformed.
B) Some of the chemical potential energy is destroyed during the energy transformation.
C) Some of the chemical potential energy is transformed into heat energy as well as kinetic energy.
D) Conservation of energy also implies that some of the chemical potential energy is conserved or not used to run the fan.
It might be c, because he came up with the plum pudding model. or it might be that atoms of the same element are identical, but that's not true cuz ions are different and isotopes are different.
