The Main Idea
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. An easy way to predict energy change is to look at thermal energy and how that changes when two substances of different temperatures interact

A Mathematical Model
∆Et =mC∆T=Q m is the mass of the object, usually in grams because C has units of J/g◦C C is the specific capacity, and is different for all materials. Units = J/g◦C. C for water is 4.2J/g◦C ∆T is the final temperature minus the initial temperature in ◦C

History
In 1847 James Prescott Joule gave a lecture entitled On Matter, Living Force, and Heat, and he characterized many terms that are closely related to thermal energy and heat transfer. He identified the terms latent heat and sensible heat as forms of heat each effecting distinct physical phenomena, namely the potential and kinetic energy of particles, and thermal energy transfer falls into this category. The units for energy, J, Joules, are named after James Prescott Joule, whose work led to the discovery of the first law of thermodynamics.
