Movement of Particles in 4 States of Matter Solid Liquid Gas Plasma

Solid Density = Since these atoms are so tightly packed, what is the only way they can move? HIGH

Atoms are…. Vibrating!!! So their ENERGY is… LOW

“What do you know about the SHAPE and VOLUME of a solid?” “The SHAPE and VOLUME are both DEFINITE, they do not change.”

What is a CRYSTALLINE SOLID? A solid that is made up of crystals that are arranged in a regular, repeating pattern. Examples??? Fluorite crystals Snowflakes

So what is an amorphous solid? The atoms inside of this solid are not arranged in a pattern, so they can not keep their shape permanently. Over a long period of time atoms in this solid slowly change their shape. Examples??? Wax Glass

Glass Notice how much thicker the glass is

Candle

Liquid The atoms in a liquid are more l o o s e l y packed. What do you notice about how the atoms of a liquid are packed compared to a solid? The atoms in a liquid are more l o o s e l y packed.

So Density = MEDIUM

So how would the atoms of a liquid move? The atoms are still stuck together, but they can move more freely since they have more space… So their ENERGY is… MEDIUM

How would you describe the SHAPE and VOLUME of liquids? “The SHAPE depends on the container it is in, so it can CHANGE. The VOLUME is DEFINITE though, liquids always take up the same amount of space.” How would you describe the SHAPE and VOLUME of liquids?

What are some liquids with HIGH VISCOSITY? Viscosity is… The resistance of a liquid to flow. What are some liquids with HIGH VISCOSITY? Honey Ketchup

What about some liquids that have a LOW VISCOSITY? Water Milk

Gas What do you notice about how The atoms of a liquid are packed compared to a solid? They barely touch each other at all….

So Density = LOW

How would you describe the energy of atoms inside of a gas? EXTREMELY HIGH!!

“So what about the SHAPE and VOLUME of gasses?” “Gases take the shape of whatever space and volume they are contained in. So the SHAPE and VOLUME both CHANGE, neither are definite.” “So what about the SHAPE and VOLUME of gasses?”

What phase of matter have we forgotten??? PLASMA!!! A super-heated gas, found in space. On Earth plasma found in lightning and neon signs!
