I should have wrote the Formulas in my book when my teacher told me to.

Well, can you tell me what the Law of Conservation of Energy says?

jabez177 · Answer

In physics, the law of conservation of energy states that the total energy of an isolated system remains constant—it is said to be conserved over time. Energy can neither be created nor destroyed; rather, it transforms from one form to another. For instance, chemical energy can be converted to kinetic energy in the explosion of a stick of dynamite. A consequence of the law of conservation of energy is that a perpetual motion machine of the first kind cannot exist. That is to say, no system without an external energy supply can deliver an unlimited amount of energy to its surroundings. https://en.wikipedia.org/wiki/Conservation_of_energy

Mhm. Nice copy and paste lol! And so if 750 J of chemical energy are used up, then how much energy must get converted into some other type of energy as a result of this?

lol
750? :/
