प्रश्न
Distinguish between:
Combustion and Respiration
उत्तर
- Combustion involves oxidation of carbon & hydrogen in hydrocarbons.
- It is a rapid process at high temperature.
- The equation formed in Combustion is
Hydrocarbon + Oxygen → Carbon Dioxide + Water Vapour.
CxHy + O2 → CO2 + H2O - Where as Respiration is a process, whereby living things use oxygen from the air to oxidize food substances mainly glucose, in their body cells and release energy in form of heat.
- It is a slow process at body temperature.
- The equation formed in Respiration is
Glucose + Oxygen → Carbon Dioxide + Water Vapour + Heat.
C6H12O6 + 6O2 → 6CO2 + 6H2O + Heat energy
