Predicting energy change is simple trying to figure out how energy moves throughout the universe without being created or destroyed, but simply by changing form. Energy makes everything happen, and every time something changes, there is an energy change associated with it. In a very simplistic form, you can predict that when you turn on an oven, it will get hot. Energy is not being created because the temperature increases, the oven is just converting energy from electricity into heat, and we predict that the temperature of the oven will increase. | |||
