STATES OF MATTER

States of Matter Title: States of Matter
Problem: How do solids, liquids, and gases differ in the motion of their particles? Hypothesis/Initial Thoughts:

There are Four States of Matter
We will focus on the main 3 Solid Liquid Gas

Data/Observation: Use the information in this presentation to take notes and fill in the table on solid, liquid, and gas Do not glue in your table until we are finished with notes

STATES OF MATTER Based on particle arrangement energy of particles
distance between particles

Change of State A compound or element can move from one state to another, but can still be the same substance. How can this happen? The answer lies in the motion of the atoms in matter. Temperature or pressure changes state can change Energy (heat) added  atoms move faster energy (heat) taken away  atoms move slower.

Kinetic Theory of Matter
Matter is made up of particles which are in continual random motion.

STATES OF MATTER SOLIDS
Particles of solids vibrate back and forth but are closely locked in position. Solids have a definite shape and a definite volume. Heat

STATES OF MATTER LIQUID
Particles of liquids are tightly packed, but are far enough apart to slide over one another, allowing liquids to flow. Liquids have an indefinite shape and a definite volume. Heat

STATES OF MATTER GAS Particles of gases are very far apart and move freely (idependently). Gases have an indefinite shape and an indefinite volume. Heat

PHASE CHANGES Gas Loss in heat Liquid Gain in heat Solid Vaporization
CONDENSATION DEPOSITION Vaporization Liquid Gain in heat FREEZING Sublimation Melting Solid

What is the fourth state of matter?
Plasma You do not need to take notes This is for your information only

Will everything just be a gas?
What happens if you raise the temperature to super-high levels… between 1000°C and 1,000,000,000°C ? Will everything just be a gas?

STATES OF MATTER PLASMA
A plasma is an ionized gas. A plasma is a very good conductor of electricity and is affected by magnetic fields. Plasmas, like gases have an indefinite shape and an indefinite volume. Plasma is the common state of matter

STATES OF MATTER LIQUID PLASMA SOLID GAS
Tightly packed, in a regular pattern Vibrate, but do not move from place to place Close together with no regular arrangement. Vibrate, move about, and slide past each other Well separated with no regular arrangement. Vibrate and move freely at high speeds Has no definite volume or shape and is composed of electrical charged particles

Some places where plasmas are found…
Flames

Lightning

Aurora (Northern Lights)

Plasma Lamp

The Sun is an example of a star in its plasma state
The sun's enormous heat rips electrons off the hydrogen and helium molecules that make up the sun. It is a great big ball of plasma.

Arrangement of particles
Review: Property Gas Liquid Solid Shape Volume Movement of particles Arrangement of particles Picture No definite shape. Takes the shape of the container No definite shape. Takes the shape of the container Definite shape No definite volume. Fills the container Definite volume. Definite volume. Move freely and independently at high speeds and collide frequently Collide and slide past each other Can only vibrate Well separated with no regular arrangement Close together with no regular arrangement Tightly packed in a regular pattern
