Study Notes
Photosynthesis
- Photosynthesis is the process where green plants make glucose using carbon dioxide, water, and light energy
- Chlorophyll, a green pigment, absorbs sunlight for this process
- Equation: 6CO₂ + 6H₂O + Sunlight → C₆H₁₂O₆ + 6O₂
Respiration
- Respiration is the process where living organisms break down glucose to release energy, carbon dioxide, and water.
- This process occurs in the presence of oxygen
- Equation: C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + 2880 kJ
Air Pressure
- Air pressure is the weight of the air above a specific location
- It is caused by gravity pulling the air toward the Earth's center
- Air pressure decreases as you move further away from the Earth's surface
- Lighter gases like hydrogen and helium are further from the surface, while heavier gases like carbon dioxide, oxygen, and nitrogen are closer to the surface
