What to Focus On

  • Air is present in atmosphere, water, and soil.
  • We cannot see air because it is colourless, odourless, and transparent.
  • Fast-moving air is called wind.
  • Nitrogen is the most abundant gas in air.
  • Oxygen supports life and burning.
  • Carbon dioxide is essential for photosynthesis.
  • Oxygen is essential for respiration and burning.
  • Nitrogen is used to make proteins and fertilizers.
  • Carbon dioxide is used in photosynthesis and fire extinguishers.

Common Mistakes to Avoid

Plants only take in carbon dioxide and give out oxygen — they don’t need oxygen for respiration.

Air is an element, not a mixture.

Oxygen is the most abundant gas in the atmosphere.

Memory Tips

Composition of air by volume: Nitrogen (78%), Oxygen (21%), Carbon dioxide (0.03–0.04%), Inert gases (0.9%), Water vapour and dust (variable)

Oxygen supports burning and respiration; Nitrogen controls burning

Air is a mixture, not a compound

Photosynthesis: CO₂ + Water → Glucose + Oxygen (in sunlight, chlorophyll)
