Opening Assignment Finish these sentences… 1. The three states of matter (solid, liquid and gas) depend on _________________. 2. To change states of matter (to go from a solid to a liquid, or a liquid to a solid, all you have to do is_____________ Indicate if the sentence is T or F. If F, change the underline word so it is true. 3. When a gas turns to a liquid, its called evaporation. 4. The freezing point is the temperature that a liquid turns to a gas.

STATES OF MATTER

STATES OF MATTER What are the states of matter?
Three common state of Matter on Earth 1. Solid 2. Liquid 3. Gas 4. Plasma

STATES OF MATTER particle arrangement energy of particles
What’s different between the three different states of matter? particle arrangement energy of particles distance between particles Does it have a definite or indefinite Shape? Does it have a definite or indefinite volume?

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

STATES OF MATTER SOLIDS
Particles of solids are tightly packed, vibrating about a fixed position. Solids have a definite shape and a definite volume. Low energy! Heat

STATES OF MATTER LIQUID
Particles of liquids are tightly packed, but are far enough apart to slide over one another. Liquids have an indefinite shape and a definite volume. More energy than solids but less energy than gasses! Heat

STATES OF MATTER GAS Particles of gases are very far apart and move freely. Gases have an indefinite shape and an indefinite volume. High energy! Heat

Will everything just be a gas?
But what happens if you raise the temperature to super-high levels… between 1000°C and 1,000,000,000°C ? (1832 °F and 180,000,000,032°F 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 most common state of matter in the universe

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

Neon lights Man-made plasmas like neon and fluorescent lights.
Inside the long tube is a gas. Electricity flows through the tube when the light is turned on. The electricity acts as an energy source and charges up the gas. This charging and exciting of the atoms creates glowing plasma inside the bulb. The electricity helps to strip the gas molecules of their electrons.

Some other places where plasmas are found…
1. Flames

2. Lightning

3. Aurora (Northern Lights)

The Sun is an example of a star in its plasma state
