PHYSICAL AND CHEMICAL CHANGES!!!!
By: Chloe Hale-1st Period
Physical Properties
Any characteristic of a material that can be observed or measured without changing the identity of the material.
Examples:
- Color and shape
- Length and mass
- Volume and density (D=M/V)
Physical Changes
The physical properties of a substance does not change.
Examples:
- Changing from one state of matter to another (Ice melts to liquid-liquid boils to steam)
- Melting 0 degrees C, and Boiling Point 100 degrees C.
- Slicing bread, melting ice, mowing lawn
Chemical Properties
Any characteristic that gives a substance the ability to undergo a change that results in a new substance.
Example:
- Flammability (Ability to burn)
- Reacts with oxygen (Ability to rust)
- Reacts with light (Pictures being developed)
- Reacts with water (medicine dissolving in water)
Chemical Changes
A change in the identity of a substance due to the chemical properties of that substance.
Example:
- 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)
