 * =__I <3 YOU__ **ASSIGNMENT 1: Physical and Chemical Properties and Changes**=





include: appearance, texture, color, odor, melting point, boiling point, solubility, polarity, and many others. //(Like the car above)//
 * Physical properties** can be observed or measured without changing the composition of matter. Physical properties are used to observe and describe matter.

//(Like the ice cube above)//
 * physical change** takes place without any changes in molecular composition. The same element or compound is present before and after the change. The same molecule is present through out the changes. Physical changes are related to physical properties since some measurements require that changes be made.

//(like the fire above)// //**chemical change,**// the substances are altered chemically and display different physical and chemical properties after the change. When a chemical change occurs new substance(s) are formed through a reorganization of the atoms. A chemical change is irreversible. (Like the fire works above)
 * Chemical properties** of matter describes its "potential" to undergo some chemical change or reaction by virtue of its composition. What elements, electrons, and bonding are present to give the potential for chemical change.
