Title: CO2 and greenhouse effect


1
CO2 and greenhouse effect
  • Katerina Vítková
  • aneta Pavlícková

2
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
3
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.
surrounding - okolí
11
A part of energy is emitted into the space but a
part is coming back and warming the Earth.
