Day 33 Chapter 3.1 Solids, Liquids, and Gases

Pick up the following:3.1 Notes handout

is anything that has mass and takes up spaceis classified into one of five states of matter Solid Liquid Gas Plasma BEC

Matter

Kinetic Energy (KE)

Energy an object has due to its motion.Faster the object moves, greater the KE

This is used to classify anything into one of the four common states of matter.

Kinetic Theory of Matter

All matter is composed of tiny particles.All particles of matter are in constant

motion. Motion = temperature. Increased

temperature means increased particle motion.

Solids, liquids, and gases differ in the freedom of motion of their particles and the extent to which their particles interact.

Kinetic Theory of Matter States:

DEFINITE SHAPE and a DEFINITE VOLUME.Atoms are spaced very close together. Atoms only have enough room to vibrate in a fixed location, cannot move around.

Solids

Have no definite shape, they take the shape of the container they’re in. Liquids particles can slide over and around one another. Have a definite volume.Particles that make up a liquid have more KE energy thus more motion than a solid.

Liquids

LiquidsForces of attraction keep the

molecules together, such as in water.

GasesHave NO DEFINITE SHAPE and NO DEFINITE VOLUME.Gases will expand to fill the entire room or can be compressed into a small cylinder.

Gases have the greatest amount of KE, (due to the highest temp) . The particles have freedom to completely separate from one another.

Gases

It is an IONIZED GAS, which is a mix of free electrons and positive charged ions.

Plasma

Ne atoms

Glass is filled with Neon gas (atoms). An electric current is run through the tube, exciting the gas. This releases the electrons and light is given off, forming a plasma.

Plug it into the wall

Plasma as a Neon Light

Plasmas are the most common state of matter in the universe (99%) They are found in …

Sun and Stars Lightning

Neon lights Plasma TV

And several other sources…

Examples of Plasmas

Plasma

Let’s watch a little video about Plasma

BECThe Fifth State of Matter, the Bose-Einstein Condensate, occurs only at really low temperatures (-273° Celsius – 0 Kelvin)At this temperature, the atoms in a substance begin to move as one.Video link

Draw a diagram of a solid, liquid, and gas. Please draw the particles and use arrows to show the motion of the particles in relationship to one another. States of Matter simulation. States of matterStates of matter
