The law that heat is a form of energy, and the total

amount of energy of all kinds in an isolated system is

constant; it is an application of the principle of

conservation of energy. Also known as conservation of

energy.

A straight line that best represents all data points of a

scatter plot. This line may pass through some, all, or

none of the points displayed by the scatter plot. Also

referred to as a Trend Line or Regression Line.

  Life Cycle

• R-value

The process by which energy is transmitted through a

medium, including empty space, as electromagnetic

waves. This energy travels at the speed of light. This is

also referred to as electromagnetic radiation.
