Matter |
Any substance that occupies space and has weight (mass) |
|
|
What are the three characteristics of Matter? |
- solid - liquid - gas |
|
|
Air |
78% nitrogen, 21% o2, 1% inert gases |
|
|
Density |
Amount of O2 in any given space |
|
|
What happens when density increases? |
1. Altitude decreases 2. Humidity decreases 3. Temp decreases |
|
|
What results happen when density increases? |
Lean carburation |
|
|
What causes Density decrease |
1. Altitude increases 2. Humidity increases 3. Temperature increases |
|
|
What affect happens when density decreases? |
Rich carburation |
|
|
What is Boyle's law? |
Tells us that when a gas is compressed, its temp an psi increase. The more bass that is compressed,the greater the temp and psi, an each time you decrease the volume of gas by one half, you double the psi. |
|
|
Momentum (kenetic energy ) |
The energy within a moving object. Mass x velocity (weight x speed) |
|
|
Whats the law of inertia? |
Anything at rest or in motion remains in that state till acted on by an outside force. |
|
|
What are the 2 types of energy? |
1. Potential energy - stored energy like a charged battery or can of gas 2. Active energy (or kinetic energy ) - energy that's in use or motion |
|
|
Carbon monoxide (Co) |
Caused by partially burned fuel during the combustion process |
|
|
Hydrocarbons (hc) |
Result of unburned or raw fuel |
|
|
Carbon dioxide (co2) |
The result of complete combustion |
|
|
Oxides of nitrogen (nox) |
Forms of oxidized nitrogen resulting from extremely high combustion temps |
