States of Matter

What is Matter? Matter is anything that has mass of that takes up space Matter is found in 4 different states 1. Solid 2. Liquid 3. Gas 4. Plasma

Ways to describe Matter We can describe matter by smell, color, texture, odor and other ways your senses perceive things We can use measurements to describe it as well Mass=the Typical amount of matter in an object units are g, kg Volume=the Typical units are ml, L (liquids) cm 3 or m 3 (solids) Density=the D=M/V amount of space the object takes up mass per unit volume of a substance

Atoms and Particles All mass is made up of atoms (the smallest unit of matter) Particles can refer to atoms, molecules (groups of atoms)

Atoms vs Molecules vs Elements Atom refers to the single smallest part of mass Molecule refers to groups of atoms joined together (either the same type of atoms or different ones) Element refers to only one type of atom, whether it is a single atom or has multiple joined together

Solids A solid has a definite shape and a definite volume. The particles in a solid are very close together and particles move very slowly (simply vibrate) The arrangement of particles can determine different properties

Liquids A Liquid is matter with a definite volume but no definite shape The particles in a liquid is faster than a solid and slip past each other This allows for particles to flow and occupy the shape of their containers

Viscosity is a measurement of a liquids resistance to flow. For example Honey has a HIGH viscosity and water has a LOW viscosity

Gases A gas is matter that has no definite volume and no definite shape Particles are far apart and move freely, they spread out and occupy fill any space

Plasma Is the most common state of matter in the universe Is high energy matter consisting of positively and negatively charged particles. Not common on this planet but found in the Sun and in lightning flashes
