Why are the properties of mixtures and fluids and their
uses important to us?
Matter is anything has mass and takes up space (has volume)
What is matter?
Matter is anything has mass and takes up space (has volume)
There are three different states or phases of matter:

There are three different states or phases of matter: Solid – definite shape and volume

There are three different states or phases of matter: Solid – definite shape and volume Liquid – no definite shape but definite volume

There are three different states or phases of matter: Solid – definite shape and volume Liquid – no definite shape but definite volume Gas – no definite shape or volume
What is matter?
In order to understand further the properties of these phases, you need to get down to the particle level.
The Particle Model of Matter
The particle model has 3 key ideas:
The Particle Model of Matter
The particle model has 3 key ideas:1) All substances are made up of tiny particles.
The Particle Model of Matter
The particle model has 3 key ideas:1) All substances are made up of tiny particles.2) The particles are always in motion. They will
move faster as energy is added or slow down as energy is taken away.

3) The particles are always colliding.

Actually, there are 2 more key ideas but we’ll get to those later…
The Particle Model of Matter
Solids Particles are tightly packed and moving with
mainly a vibrational motion. Very low energy.
Applying the Particle Model to Phases of Matter
Liquids Particles are vibrating and rotating and so
there are bigger spaces between them. The particles don’t form rigid clumps which is
why they take the shape of the container they are in.
Applying the Particle Model to Phases of Matter
Gases Particles have very high energy and so have
rotational, vibrational and translational movement.
There are large spaces between the particles.
Applying the Particle Model to Phases of Matter
As the particles gain or lose energy, they move closer or further apart.
This change in energy results in changes of state.

Changes of State
As the particles gain or lose energy, they move closer or further apart.
This change in energy results in changes of state.
Changes of State
True and False Get up and do simulations. Fish Relay Race White boards practice
