State Beer-Lambert's law?

Beer's law (sometimes called the Beer-Lambert law) states that the absorbance is proportional to the path length, b, through the sample and the concentration of the absorbing species, c: A α b · c. The proportionality constant is sometimes given the symbol a, giving Beer's law an alphabetic look: A = a · b · c.

Heat is involved in chemical change in two ways; chemical changes either result in heat being added to or removed from an object, and chemical changes require a certain amount of heat before they can take place.
