States of Matter

Having trouble with states of matter? Never fear! The states of matter are solids, liquids, gases and plasma.

Solids are one of the states of matter. Solids have definite shape and volume. No matter how much you pound on the table, the table is still going to have the same volume. There are two types of solids; crystalline and noncrystalline. Crystalline solids have repeating geometric patterns. Noncrystalline solids are not made of crystals but are amorphous. Amorphous is having no form. Amorphous solids are like plastic and glass. Some examples are snow, people, walls, bricks, phones, pens, valentines, paper, and etc.
Liquids are another state of matter. Liquids take the shape of the container. Whether it’s the ocean floor or a sippy cup, the liquid takes the form. A liquid can never be squeezed to a smaller volume. Liquids always have more motion. Liquids have more kinetic energy than a solid. Some examples are water, blood, syrup, oil, milk, and etc.
Gases are “springy”. The cool thing about gases is that it can change shape and volume. The particles can completely separate from one another. That’s called diffusion. Diffusion is when you spray perfume (or cologne) in a few seconds you can smell it across the room. That’s why they ask you not to spray stuff on the bus. Particles can move any where they please which is what makes a gas unique. Gases also have more kinetic energy than a solid or a liquid. Some examples are water vapor, smog, fog, perfume, and etc.
Plasma is the last state of matter. Did you know that plasma is the most common form of matter? Plasma is also found in the stars! Plasma is a mixture of positive and negative charged particles. As the particles are heated, the particles are split into smaller particles! Do you remember the lava lamps hippies used? Well, plasma was the fluorescent lava in the lamp! That’s cool science! Some examples are
Gases in discharge tubes (fluorescent lamps and neon signs), Welding arcs, Lightning, Auroras, The upper atmosphere (the ionosphere), Stars and the Sun, the solar wind, interstellar gas clouds, the fireball made by a nuclear weapon, Comet tails and etc. Examples from General Chemistry Online from the Author: Fred Senese senese@antoine.frostburg.edu
You probably heard me mention before about kinetic energy. The kinetic theory of matter is the theory that particles are in constant motion. A gas has the most kinetic energy because the particles move the fastest. A solid on the other hand have little kinetic energy.

Well I hope these facts on states of matter will help you!

Here are your notes, fill in the blank, for the gas laws...

Here is your Charles vs. Boyle chart. Hint: see if you can find the answers in the chart.
