CO2

• gas
• solid - dry ice
• liquid- solvent for many organic compounds

• Chemical and physical properties
• colorless, tasteless, odourless
• at high concentration - suffocating gas

Suffocating gas dusivý plyn

Application CO2

• Carbon dioxide is used to produce
• Inorganic carbonate, Methanol, Polycarbonate,
  Polyurethane
• Bakery leavening agent, baking soda
• Food industry soft drink, soda water
• Welding gas
• Fire extinguishers, especially for electrical
  fires
• Plants require carbon dioxide to conduct
  photosynthesis

Greenhouse effect

• Greenhouse gases

• The atmosphere warming is caused by influence
  of increasing amount CO2 and other greenhouse
  gases.

Greenhouse effect skleníkový efekt
5

• The Sun energy penetrating to the earth.

penetrating - proniknout
6

• The earth's surface absorbs the solar energy
  but part of energy comes back into the space.

space - vesmír
7

• Coming luminous energy warming the Earth which
  then emits energy in the form of infrared
  radiation or a heat.

Infrared radiation infracervené zárení
8

• A part of this IR radiations coming back to the
  earth again which is caused by the help of
  greenhouse gases included in the atmosphere.

9
Infrared radiation has a long wavelength.
Greenhouse gases unlike of the other gases
include molecules which absorb this radiation.
wavelength vlnová délka
10
The molecules absorb the infrared radiation and
then re-emit it back in all direction into the
surroundings.

A part of energy is emitted into the space but a
part is coming back and warming the Earth.
