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

|
Definate shape & volume.
|
|
|
What are the properties of a liquid?
|

|
|
|
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?
|
Buoyancy.
|
|
|
If the bouyant force equals the objects weight the object ______.
|
Floats.
|
|
|
If the bouyant force is less than the objects weight the object will _____.
|
Sink.
|
|
|
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.
|
Sink.
|
|
|
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 ____.
|
Liquid.
|
|
|
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 ______.
|
Thrown.
|
|
|
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.
