=**WHAT IS THE DIFFERENCE BETWEEN A CHEMICAL AND PHYSICAL CHANGE? **= =**Contributed By: AJ B. **= =**Date of Publication: September 30, 2011** =

 A chemical change is the process where something (Normally either chemical element or compound) changes into any number of different substances. While on the other hand a Physical change is when an object has a change that won’t destroy or change the natural chemical compound found in the object. They are different for many reasons, one being the fact that a chemical change is creating a compound that couldn’t have been found in or on the object before. However a physical change just takes what is there and mixes it to make something out of it.  Figure 1: Physical and Chemical changes __Diet Coke and Mentos Experiment __

__What you’ll need __ 2 liter bottle of diet coke 5 Mentos __What to do __ 1) Take the cap off the coke bottle 2) Get 5 Mentos ready to drop in the bottle 3) Drop the 5 Mentos into the bottle of diet coke and immediately run away

4) Watch the explosion!
