Carbon Atom and Energy Sources

Question 1

Properties of Carbon Atom

Answer 1

The diameter of a carbon atom is extremely small.
An individual carbon atom is shorter than the wavelengths of visible light.

Question 2

ncorporation of Carbon in Organic Molecules

Answer 2

Carbon is ‘fixed’ by plants through photosynthesis.
Carbon is stored in various forms after a plant dies before being released into the atmosphere as CO2.

Question 3

Fossil Fuels and Carbon Reserves

Answer 3

Fossil fuels are energy stored in carbon molecules fixed through photosynthesis millions of years ago during the Carboniferous and Jurassic periods.
Coal, oil, and gas reserves were formed during these periods.

Question 4

Energy Sources and Carbon Content

Answer 4

The diameter of a carbon atom is extremely small.
An individual carbon atom is shorter than the wavelengths of visible light.

Question 5

Significance of Carbon in Fuel Sources

Answer 5

Carbon is a crucial component of fuel sources.
Fossil fuels are ancient carbon reserves fixed by plants millions of years ago.

Question 6

Importance of Carbon Atom Size

Answer 6

* The food we eat and the wood we burn are produced relatively quickly
