What is Boyle's Law?
Volume of a gas varies inversely with pressure.


Large volume, low pressure. Or, small volume high pressure.
What is Charles' Law?
Volume of a gas varies directly with temperature.

Ex. Small volume, low temperature. Or, large volume, high temperature.
What are the four states of matter?
Solid, liquid, gas, plasma.
What are the particle descriptions of a solid?
- Tightly packed.
- Vibrate in fixed positions.
- Strong attractive forces.
- Least amount of energy.
What are the particle descriptions of a liquid?
- Closely arranged.
- Able to freely move around each other.
- Moderately strong attractive force.
- More energy than a solid.
What are the particle descriptions of a gas?
- Very far apart
- Moves rapidly & randomly
- Weak attractive force
- Greatest energy
What are the particle descriptions of a plasma?
- Gas like mixture of negative & positively charged particles.
- Very far apart, high energy.
- Affected by electric & magnetic fields.
- Exists at extremely high temperatures.
What are the properties of a solid?
Definate shape & volume.
What are the properties of a liquid?
Definate volume, no definate shape, and takes the shape of the container it is in.
What are the properties of gas?
No definate shape or volume, occupying shape & volume of container.
What are the properties of plasma?
No definate shape or volume, occupies shape and volume of the container it is in.
What are fluids?
Gases and liquids?
What is the upward force that fluids exert on?
If the bouyant force equals the objects weight the object ______.
If the bouyant force is less than the objects weight the object will _____.
What is Archimedes' Principle?
The bouyant force on an object in a fluid is equal to the weight of the fluid displaced by the object.
An object will ____ in a fluid until it displaces its own weight in fluid.
Pressure applied to a fluid is transmitted unchanged throughout the fluid.

What principle is this?
Pascal's Principle.
A force exerted on a small area causes a pressure in the ____.
What is Bernoulli's Principle?
As the velocity of a fluid increases, the pressure exerted by the fluid decreases.
Air moves faster along the side of a spinning ball that is moving away from the direction ______.
What is thermal expansion?
When all matter expands as it gets hotter and contracts when it cools.
What is the kinetic theory of matter?
The theory that all matter is made up of tiny particles that are in constant motion.
What is evaporation?
When a liquid changes to a gas gradually at temperatures below the boiling point.
When does condensation take placE?
When a gas changes to a liquid.
The heat of vaporization is...
The amound of energy needed to change a material from liquid to a gas.
What is a pascal (Pa)?
The SI unit of pressure.
What is pressure?
The amount of force exerted per unit of area.
The amound of the boyant force determines whether an object will _________in a fluid
