6.1 Air Pollution

Question 1

photochemical smog

Answer 1

mixture of air pollutants that is produced when nitrogen oxides and VOCs react in the presence of ultraviolet radiation

Question 2

what does photochemical smog look like

Answer 2

brown haze

Question 3

where do you usually see photochemical smog

Answer 3

urban areas with lots of motor vehicles and fossil fuel emissions

Question 4

what are the products of photochemical smog

Answer 4

ozone
nitric acid
aldehydes
peroxyacyl nitrates

Question 5

what are nitrous oxides

Answer 5

NO and NO2; nitrous oxide and dioxide respectively

Question 6

how are nitrous oxides released into the atmosphere

Answer 6

burning of fossil fuels

Question 7

Volatile organic hydrocarbons

Answer 7

a group of harmful compounds that vaporize quickly and easily into the air

Question 8

where do VOCs come from

Answer 8

natural sources
industrial products

Question 9

what type of air quality do VOCs mess up and why

Answer 9

indoor bc VOC containing products are usually for the inside

Question 10

ozone

Answer 10

O3

Question 11

ozone forms how

Answer 11

when a nitrous oxide and VOCs are exposed to uv radiation

Question 12

when is ozone usually present

Answer 12

when its like rush hour and shi bc cars and stuff so ozone is made

Question 13

why is ozone bad

Answer 13

bc it creates a health risk bc its supposed to be in the atmosphere not on earth

Question 14

photochemical smog good or bad and why

Answer 14

can cause health issues like coughing difficulty breathing and rly bad stuff

Question 15

what is the relative temp of photochemical smog

Answer 15

hot

Question 16

is the fact that photochemical smog is hot good or bad and why

Answer 16

bad bc it traps harmful poisonous gasses which can be harmful to organisms

Question 17

particulates

Answer 17

particles so small that they stay in the air

Question 18

volatile organic compounds

Answer 18

substances that form gasses at room temp

Question 19

example of volatile organic compounds

Answer 19

formaldehyde

Question 20

example of particulate

Answer 20

asbestos

Question 21

why are particulates bad

Answer 21

bc they go into ur lungs and cells and stuff and MESS EM UP

Question 22

how does combustion cause indoor pollution

Answer 22

creates carbon dioxide nitrous oxides and other pollution

Question 23

how is mold a natural pollutant

Answer 23

it has fungus that floats in the air and can be bad for your lungs

Question 24

sources of indoor pollution

Answer 24

house, outside, combustion

Question 25

what happens when thermal inversion occurs

Answer 25

there are calm winds and ground fog bc the cold air is trapped so its the only one that circulates

Question 26

when does thermal inversion occur

Answer 26

when a layer of warm air forms over a layer of cool air

Question 27

is thermal inversion good or bad and why

Answer 27

bad bc This inversion prevents the normal vertical mixing of air, trapping pollutants and moisture near the ground, leading to potentially hazardous air quality conditions.

Question 28

what is a common cause of nitrous oxide emmision and therefore when does emmision spike

Answer 28

during rush hour bc cars cause it
