Physical and Chemical Changes
By:Magen Stiefer
Physical Properties
Any characteristics of a material that can be observed or measured without changing the identity of the material.
Examples-color & shape, length &mass,volume & density.
Physical Changes
The physical properties of a substance change,but the identity of the substance does not change.
Examples-slicing bread,breaking glass,ripping paper.
Chemical Properties
Any characteristics that give a substance the ability to under go a change that results in a new substance.
Examples-flammability[ability to burn],reacts with oxygen[ability to rust],reacts to light[pictures being developed],reacts with water[medicine dissolving in water]
Chemical Changes
A change in the identity of a new substance due to the chemical properties of that substance.[You have a new substance] [Is it reversible] NO IT IS NOT!!!!!!
Examples:Flammability[fire burning to ash],reacts to oxygen[fruit rotting]heat&light[vitamins can change exposed to light],electricity[water can be broken down with electricity]
