Slide2Standards
6.P.2.2 - Explain the effect of heat on the motion of atoms through a description of what happens to particles during a change in phase.
Slide3I can answer these questions:
Do atoms move faster or slower when they are heated
Do atoms move faster or slower when they are cooled
What happens to atoms when they go from a solid to a liquid
What happens to atoms when they go from a liquid to a gas
What happens when the phase changes are reverse gas to liquid to solid
Slide4How many state of matter?
Only 3 right?
WRONG!
There are 5 states of matter
Slide53 common states
Solid
Liquid
Gas
Slide62 not so common states
Plasma
Bose-Einstein
Slide7How are the states different?
The difference between each state is how tightly or loosely packed the atoms are to each other
Slide8Solid
Solids are packed extremely tight together. They take a specific shape.
Slide9WEIRD SCIENCE
Even though you can’t see it, the atoms in a solid are still vibrating! Weird, so a solid is moving?! CRAZY
Slide10Liquid
In a liquid the atoms are further apart.
Slide11WEIRD SCIENCE
A liquid does not have a shape. In fact it takes the shape of whatever is holding it.
Slide12Gas
Gases are moving
extremely
fast.
The atoms are bouncing all around all the time. They take up all the space in an area until they get more room.
Slide13WEIRD SCIENCE
In the entire gy
m
we could have only two gas atoms. They would bounce around so much and so quickly that no more gas atoms could fit. CRAZY!!
Slide14Plasma
Plasma is the next step after a gas. Enough energy is put into the gas that electrons break free.
Plasma is the most common state in the universe
Slide15WEIRD SCIENCE
The largest amount of plasma near us is the Sun. It is a great big ball of plasma.
Slide16Bose-Einstein
This state is what happens with a black hole. All the atoms lose their energy and clump together.
Slide17WEIRD SCIENCE
Bose-Einstein were two
people.
Satyendra
Bose and Albert Einstein
This state happens at super cold temperatures.
Slide18Phase Change
A phase change happens when atoms are either heated up or cooled down.
The best example of this is with water:
Ice to liquid water to gas
Slide19Heating
When the atoms in a solid are heated they move faster and begin spread apart until they reach the new phase – liquid
When the atoms in a liquid are heated they move faster and begin to spread apart until they reach a new phase - gas
Slide20Cooling
As a gas is cooled the atoms begin to move more slowly and start get closer together until it becomes a liquid.
As a liquid cools the atoms begin to move more slowly and start to get closer until it becomes a solid.
Slide21WEIRD SCIENCE
Most things need to go through each phase change to go from a solid to a gas. Which means they have to become a liquid.
But not dry ice (carbon dioxide) it can go from a solid to a gas and not become a liquid.
