Everything that has mass and volume is called matter.

All matter, regardless of state, undergoes

physical

and

chemical changes.

•The substance changes state •It DOES NOT change its chemical composition. •Example: water freezing into ice •The form or appearance has changed, but the properties of that substance are the same.

• Melting• Boiling• Vapor pressure• Color• State of matter

• Density • Electrical conductivity• Solubility

•Occurs when a substance changes into something new.

•This occurs due to heating, chemical reaction, etc.

•You can tell a chemical change has occurred if the density, melting point or freezing point of

the original substance changes.

•Many common signs of a chemical change can be seen (bubbles forming, mass changed, etc).
