__**Write a paragraph about energy**__

Energy is power derived from the utilization of physical or chemical resources, especially to provide light and heat or to work machines. Energy comes in multiple forms. It can also be converted from one form to another.The two most common forms of energy are Kinetic and Potential energy. Another big idea in thermodynamics is the concept of energy that changes the molecules. For example, when you change the state of a system (solid, liquid, gas), the atoms and/or molecules have different arrangements and degrees of freedom to move. That increase in freedom is called entropy. Atoms are able to move around more and there is more activity. That increase in freedom is an increase in entropy.
