Density
|
The amount of matter in a given volume of a material; mass per volume (volume divided into mass=density)
|
|
|
How to calculate Density
|
Mass
----------- Volume |
|
|
Fluid
|
A substance that flows or takes the shape of a container, it could be liquids or gases.
|
|
|
Convection Cell
|
A cycle caused by convection when cool, denser material sinks and replaces warmer, less dense material.
|
|
|
Mass
|
The amount of matter in an object.
|
|
|
Volume
|
The amount of space an object takes up.
|
|
|
How does radiation travel?
|
Radiation travels as waves or rays through space or air. It can be visible or invisible. The source and the receiver of the energy are NOT in direct contact.
|
|
|
Conduction
|
Energy transfer that occurs between molecules or atoms when they touch each other.
|
|
|
Reradiation
|
When matter releases heat energy it has absorbed.
|
|
|
Precipitation
|
A form of water, such as rain, snow, or sleet, which condenses from the atmosphere, becomes too heavy to remain suspended, and falls to the the Earth's surface.
|
|
|
Convection
|
The circualation of fluid (liquid or gas) that results from energy transfer; warm air rises and cool masses sink.
|
|
|
Describe the energy of gases
|
Gases have atoms or molecules that have HIGH energy and move around randomly, freely, and independently
|
|
|
Describe the energy of liquids
|
Liquids have atoms weak in association with ech other-the molecules pass freely past and around one another
|
|
|
Describe the energy of solids
|
Solids have molecules that are bonded to one another-they are NOT free to move with respect to one another
|
|
|
What is the MOST important factor in the atmosphere when we consider weather?
|
Water vapopr because without it we would not have clouds or rain.
|
|
|
What is the most important factor affecting the density of matter?
|
Energy
|
|
|
The more closely atoms are packed...
|
the greater the mass
|
