- C1 - Air Quality
- The Earth's Atmosphire
- Carbon dioxide
- Water Vapour
- Oxygen
- Nitrogen
- Noble Gases
- What the Earth's Atmosphere is made out of
- 78% Nitrogen
- 21% Oxygen
- 1% Argon
- carbon dioxide 0.038%
- Water Vapour 0-4%
- Measuring Pollutants
- Concentration is measured in parts per million (ppm) or parts per Billion (ppb)
- Elements
- if a solid, liquid or gas is made up of only one type of atom it is called an element
- Compounds
- Compounds are different to elements. Compounds contain different atoms
- Examples
- Methane CH4
- Water H20
- Carbon Dioxide Co2
- Sulphuric Acid H2SO4
- Pollution
- What Happens to Pollution?
- Carbon Dioxide Causes Global warming but some of it can be removed by plants by using Photosynthesis or reactions with seawater.
- sulfer dioxide and nitrogen dioxide cause acid rain which damages trees and buildings
- particulates can make buildings dirty and worsen breathing difficulties
- Removing Air Pollution
- Use less electricity/ central heating
- Remove Toxic chemicals before or after they are burnt
- use alternative energy sources, e.g. Wind powers and Solor Pannels
- Can Kill Plants
- Harm Humans lungs
- Kills Plants
- Causes acid tain and is thought to contribute to global warming
- Main Pollutants
- carbon monoxide is a poisonous gay it reacts with human blood and can kill you
- sulfur dioxide causes acid rainsulfur dioxide causes acid rain
- Nitrogen dioxide causes acid rain, breathing problems and increase asthma problems
- particulates of carbon make things dirty and make breathing problems worse
- What Happens to Pollution?
- Catalytic Converter
- use alternative energy sources, e.g. Wind powers and Solor Pannels
- nitrogen monoxide + carbon monoxide -------> nitrogen + carbon monoxide
- The Earth's Atmosphire
