MATTER Chemistry Biology Earth Sciences Matter Astronomy Physics

What is Matter? __________ Almost everything around us is matter including air and other gases. If you add objects together their total mass equals the added mass of each object Energy is not matter.

Mass and Volume _________ If you add more matter into an object, its mass will increase Volume is the amount of space an object takes up The amount of mass in a particular volume is density (more later)

The Particle Theory – The 5 Rules of MATTER

Rule #1 All matter is composed of particles _________ If you take a substance and break it into successively smaller pieces, ……………

Rule #2 The particles of one substance are the same. The particles of different substances are made of different particles ___________

Rule #4 ______________ Even if a substance ………….. In theory, when this movement stops, a substance has reached its lowest possible temperature (absolute zero: -273oC) We are not currently able to do this

Rule #5 The more energy particles have, the faster they move and the higher their temperature Temperature is a measurement of the speed of the particles. Higher temperature = more speed
