Atmosphere Flashcards
Percentage of Nitrogen
78.08%
Percentage of Argon
0.93%
Percentage of Oxygen
20.95%
Nitrogen
Two nitrogen atoms bonded together with a triple bond which makes it unreactive
Oxygen
Two atoms bonded together, highly reactive, primarily produced by photosynthesis, done by plants and some bacteria
Argon
An unreactive gas that is only one atom
Density
The heaviness of an object, how closely packed the molecules are
Temperature
Measure of thermal or internal energy
Pressure
The amount of force exerted over an area
Humidity
The amount of water in the air
Physical
Pressure, density, humidity, temperature
Chemical
Properties of gases
Air Pressure
The weight of air pushing on all surfaces
O2
Oxygen
C02
Carbon Dioxide
SO4
Sulfur Dioxide
N2
Nitrogen
PPM
Parts per Million
Stage One
Hydrogen and helium were so hot and moved so fast and hot
Stage Two
Many volcanoes release water, carbon dioxide, and ammonia
Stage Three
Our modern atmosphere
Mass
The amount of stuff in an object
Solid
Set volume, set shape
Liquid
Set volume
Gas
Neither set volume or set shape
Vacuum
A three dimensional space with little/to no air pressure
Suction
Not somethin sucking; air pushing; imbalance of pressure;
Is space a vacuum
Yes
Units of Air pressure
Pounds per square inch, mm/in of mercury, kilopascals
Units of Pressure
Newton, pascal, pounds per square inch
Troposphere
1st
10k-0k
Where the air circulates and causes weather
Normal Pressure
Stratosphere
2nd 10k-50k Ozone layer is here, so it heats up Absorbs radiation Pressure drops
Mesosphere
3rd 50-80k Very cold Pressure drops Shooting stars dissolve here
Thermosphere
4th 80-120k Lots of hot particles Pressure lowers Temperature lowers
Ionosphere
Different regions in each sphere where UV rays penetrate
Has three layers E, F, D
Exosphere
5th 120k-190k Transition into space Little to no pressure Cold empty space
How does cup work
No pressure on inside so suction keeps it in
Can crush
Pressure from the outside crushed the vaccum in the can
