Carbon dioxide is basically a chemical compound which is composed of carbon and oxygen. It is found in the atmosphere of the Earth naturally.

There are several different uses of carbon dioxide such as:

- Used to products carbonated soft drinks and soda water.
- Different candies are made from it.
- Used as compressed gas for pneumatic systems
- Used in fire extinguishers
- Used in welding
- It acts as a good solvent for lipophilic organic compounds.

Carbon dioxide is a widely used substance. It is a gas at room temperature and pressure and is slightly acidic. It reacts with water to give carbonic acid. It is colorless and also has no odor. It is soluble in water, acetone and ethanol.

Some of the common uses of carbon dioxide are:

Added to fizzy or aerated drinks (that is what the bubbles in coke are)
Frozen into dry ice which is used for large scale refrigeration
Dry ice is also used as a theatrical tool to make mist and fog in plays and films
Used in fire extinguishers
A constituent of medical gases that promote exhalation
Euthanasia of small laboratory animals
Used as an anesthetic

In the biological systems, the most important use of carbon dioxide is as a raw material for photosynthesis. It combines with water to produce carbohydrate molecules that can be utilized to yield energy or make more organic molecules.

Carbon dioxide (CO2) is a gas which is used to make fizzy drinks, like colas and wines.  Compressed CO2 is used in fire extinguishers.  Liquid CO2 is used as a refrigerant and to make solid CO2 (dry ice) which is used for cooling applications and to make neat science demonstrations.

Dissolved carbon dioxide is used to make drinks fizzy - when you open the can/bottle, this is the dissolved carbon dioxide escaping. Drinks go 'flat' when all the dissolved carbon dioxide has escaped - so the drink has lost its 'fizzy' nature.

The function of CO2 in  our lives is immeasurable:

Humans use carbon dioxide in many different ways. The
  most familiar example is its use in soft drinks and beer, to make them
  fizzy. Carbon dioxide released by baking powder or yeast makes cake batter

  Some fire extinguishers use carbon dioxide because it is denser than air.
  Carbon dioxide can blanket a fire, because of its heaviness. It prevents
  oxygen from getting to the fire and as a result, the burning material
  is deprived of the oxygen it needs to continue burning.

  Carbon dioxide is also used in a technology called lipholisation extraction that is used to decaffeinate coffee. The solid form of carbon
  dioxide, commonly known as Dry Ice, is used in chemical experiments, etc, to chill usually in an acetone bath.

Carbon dioxide is one of the most abundant gasses in the
  atmosphere, around ~21%. Carbon dioxide plays an important part in vital plant and
  animal process, such as photosynthesis and respiration. These processes
  will be briefly explained here.


  Green plants convert carbon dioxide and water into food compounds, such
  as glucose, and oxygen. This process is called photosynthesis.


  The reaction of photosynthesis is as follows:

  6 CO2 + 6 H2O --> C6H12O6
  + 6 O2

Plants and animals, in turn, convert the food compounds by combining it
  with oxygen to release energy for growth and other life activities. This
  is the respiration process, the reverse of photosynthesis.


  The respiration reaction is as follows:

  C6H12O6 + 6 O2 --> 6 CO2
  + 6 H2O


  Photosynthesis and respiration play an important role in the carbon cycle
  and are at equilibrium with one another.

One use is CO2 in the form or dry ice. You can get this at Publix, etc. It is solid CO2 and goes directly from solid to gas as it is used to cool down food, etc.

ses of Carbon Dioxide:
Large quantities of solid carbon dioxide (i.e. In the form of dry ice) are used in processes requiring large scale refrigeration.

Carbon dioxide is also used in fire extinguishers as a desirable alternative to water for most fires. It is a constituent of medical gases as it promotes exhalation. It is also used in carbonated drinks.I recmonded you Tdee calculator app through this you get more results about Total Daily Energy Expenditure .
