Physical vs. Chemical Properties.
Compare and Contrast
A Physical change occurs when an object has a change that does not change their chemical composition. An evidence of Physical Change would be a change in texture, temperature, shape, etc.
- Boiling Water
- Melting Ice
- Freezing Water
A Chemical Change occurs when two different substances mix to create another substance that has a different chemical composition. An evidence of a Chemical Change would be changes in temperature (works for both), color, odor, and anything that will change it's chemical composition.
- Rusting Metal
- Burning Wood
- Baking a Cake
Precipitate- cause a substance to be deposited in solid form from a solution.
- When two liquids create a solid.(Chemical Change)
Exothermic- a reaction that cause a release of heat.
- Making Ice Cubes (Physical Change)
Endothermic- A reaction that causes or requires the absorption of heat.
- Melting Ice Cubes (Physical Change)
