1. Topic 3.4 – Compression of Fluids
Unit 2 – Mix and Flow of Matter

2. Compression
When a FORCE pushes on an object, the object is under compression
Objects under compression tend to deform in shape
Like a soccer ball when you kick it.
HUH? What does this mean?

3. A juice jug… Gas can be compressed much more than a liquid….
WHO CAN USE THIS JUICE JUG TO SHOW ME WHY THIS IS TRUE?

4. The Particle Model can Explain…
REMEMBER..
There is much more space between particles in the gas than between those in the liquid
SOOO… when a force is applied to the particles, the gas has more space to “squish” and compress.

5. Incompressible…
Materials in a liquid state can be compressed very little if at all
ALL LIQUIDS ARE SAID TO BE INCOMPRESSIBLE (they cannot be compressed easily)

6. BILL NYE TIME!
Pressure…
