3. For respiration oxygen use
Use oxygen for respire realese energy in the form of heat air to
oxidize food substances mainly gulocose in their body cells.
4. Oxygen for contibution
• It involves oxiditions ie .combination of substances like fuels with oxygen or
air generally resulting in production of heat and light.
• Fuel+oxygen-carbon dioxide+ watrer vapour +energy
• Carbon dioxide is reallesed in air as a resauklt of all burning.

6. Potosythesis
Is a process by which green plants prepare their food in the presence
of sunlight and cholorophyll.
CARBON DIOXIDE WATER IN THE PRESENCE OF
SUNLIGHTAND CHOLOROPHYLL IS CHANGED IN
CARBOHYDRATEDS AND OXYGEN IS REALESED OUT -
8. EFFECTS ON ENVOIREMENT DUE TO
CARB ON DIOXIDE
• IR RAYS AND ULTRAVOILET RAYS
• Thease rays heat up the earth.
• The uv rays from the earth surface pass through carbon dioxdide in
atmosphereir rays are prvended by carbon dioxide result-=
• The earth envoirment staying warm.

10. Water vapour ,rare gasses andpolluting gasses
• Water vapour- minimizes the rate of evopouration.
• In the atmosphere – produses rain mist etc. thereby determining climatic
conditions.
• In excess – the rain serves as a natural source of water for plants and animals
11. Advertisment, a brillent glow is seen
Fillment bulbs, the metal filament not burn in atmphere argon- argon
Xenon- in flurocent bulbs , flash bulbs and laseres.
Radon – radioactive and may fin applications in medicine .
Polluting gasses
Sulphur- causes respiratory problems
Dust
Particles-precipates rain
12. Properrties of air are found to be the air
Therefore has no definite properties.
Average properties of consituents air is amixture
