Predicting Change

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

What are the mathematical equations that allow us to model this topic. For example [math]\displaystyle{ {\frac{d\vec{p}}{dt}}_{system} = \vec{F}_{net} }[/math] where p is the momentum of the system and F is the net force from the surroundings.
