Physical & Chemical Changes
By Bailee Wilson
Physical Properties
Any characteristic of a material that can be observed and/or measured without changing the identity of the material
EXAMPLES:
- Color and Shape
- Length and Mass
- Volume and Density
Physical Changes
The physical property of a substance may change, but the identity of the substance does not change.
Examples:
- Changing From One State of Matter to the Next(Ice Melts to Liquid, Liquid Boils to Steam)
- Melting 0 Degrees and Boiling 100 degrees C
- Slicing Bread, Melting Ice, and Mowing Lawn
Chemical Properties
Any characteristic that give a substance the ability to undergo a change that results in a new substance.
EXAMPLES:
- Flammablilty (ability to burn)
- Reacts with Oxygen(ability to rust)
- Reacts with Light(pictures being developed)
- Reacts with Water(medicine dissolving in water)
Chemical Change
A change in the identity of a substance due to the chemical properties of that substance
EXAMPLES:
- Flammability(fire burning to ash)
- Reacts with Oxygen(fruit rotting)
- Heat and Light(vitamins can change exposed to light)
- Electricity(Water can be broken down with electricity)
