Combustion
What is burning?
What are smoke and fog?
definition for density
What is how tightly packed matter is in a given space?
When heat moves through a fluid and warm fluid rises up and cool fluid sinks down
What is convection?
mass is neither created or destroyed in a chemical reaction/combustion; you must begin and end with the same number of molecules
What is the law of conservation of mass?
gas produced during incomplete combustion
What is carbon monoxide?
the great smog of 1952 occurred in this European city
What is London?
formula for finding density
What is density = mass divided by volume?
black carbon or tiny particles of partially burned material that float up into the air
What is soot?
It is a weather condition where an overlaying mass of heated air prevents the circulation of air beneath it, stopping convection.
What is thermal inversion?
the number placed in front of a molecule (hint: it is written in the same size as the molecules)
What is the coefficient?
causes smog to travel great distances
What is wind?
this is happening when pollution rises up and goes over mountains
What is convection?
this number cannot be changed; changing this number would alter the molecule itself
What is the subscript?
the type of weather conditions that cause smog to get worse
What are hot and dry?
this is happening when pollution stays near the ground and doesn't get swept away
2Fe3O2H
The number of oxygen atoms in this molecule _____
What are 4?

What are reduced visibility, difficulty breathing, and heart failure, especially for the young, the elderly, and asthmatics?
