Today’s Objectives

SWBAT graph phase changes.

SWBAT describe phase changes of water.

Remember the Kinetic Molecular Theory!

In the 3 different states, particle movement is directly related to temperature

3 common states of matter

Solid – Molecules are tightly arranged

Liquid – Molecules flow over each other

Gas – Molecules are further apart and move fast

Phase Changes

Key Point #1: When you change the amount of heat energy in a substance, it will change from one state to another.

Ok, so how does it work?

Let’s say I have my beaker of ice and I add some heat…

What is going to happen to the temperature?

Of course, the temperature goes up…

DUH! Ms. Stroh, why are we doing this?So it will just keep going up right?

NO! It is about to change phase and something very interesting happens…

You are still adding the same

What is happening on a particle level during a phase change?

Key Point #2: The energy added to a

substance during a phase change is NOT used to raise the

temperature but instead to pull the

particles apart from each other

It is a transition time!

WHO’S PAYING ATTENTION?

What happens as you heat up a solid?

What happens during a phase change?

Page 19: Catalyst – September (33-10), 2009 1. Describe the Law of Conservation of Matter in your own words. 2. Kevin thinks that drinking orange juice will allow.

We have a name for the two phase change points

What do you think is the point when a solid moves to a liquid? MELTING POINT!!

What do you think is the point when a liquid turns into a gas? BOILING POINT!! (OR VAPORIZATION POINT!!)

We have a name for the two more phase change points

What do you think is the point when a gas cools to a liquid? CONDENSATION POINT!!

What do you think is the point when a liquid turns into a solid? FREEZING POINT!!

Some vocabulary

Key Point #3: You must know the four points to look out for on a phase change graph.

Heating Up: Solid Liquid = Melting Point Liquid Gas = Boiling Point

Cooling Down: Gas Liquid = Condensation Point Liquid Solid = Freezing Point

Exit Question

1. Sketch a phase change graph.

2. Explain why it makes this shape.
