What are the best absorbers of thermal radiation?
Black, dull surfaces are the best absorbers of thermal radiation because the heat doesn't reflect off it unlike shiny surfaces.
How does heat energy get from earths surface to air?
If the earth is warmer than the air, the air in contact with earth will heat the air by conduction. This now-warmer air expands and so can rise and be replaced by cooler air, which is heated in turn. This air movement is convection, so both conduction and convection allow energy to be transferred to the air above it. There is very little radiative heating of the air near the ground, but clouds do absorb (and reflect) heat from the earth by radiation in the infrared.
WHAT fuels produces the greatest quantity of CO2 per unit of heat energy produced?
natural gas
What is a gas that traps solar energy?
A gas that traps solar energy is called a greenhouse gas. The main ones are water vapour, carbon dioxide (CO2) and methane. They trap the infrared heat rising from the surface of the earth and prevent it escaping to space.
How do you trap cold air from the atmosphere?
They have these wonderful devices nowadays. They're called "picnic coolers". You might be thinking of Maxwell's Demon, but I kind of doubt it. It wouldn't work anyway. It turns out the waste heat generated by the work done by the demon in opening and shutting the gate more than offsets any possible cooling effect.
How does a greenhouse gas work?
Long wave radiation emitted by the sun reflects off earth's surface and is absorbed by heat trapping gas in the atmosphere. Nitrogen and oxygen do NOT absorb infrared radiation, but CO2, CH4, and H2O DO trap heat.
Does a catalytic converter helps to reduce the greenhouse effect?
As the catalytic converter emits CO2 and H2O in the air. The gasses absorbe infra red radiation emitted by the earth and re-radiate the energy as heat back towards the earth. So the more CO2 and H2O emitted to the air the more heat there will be. So no, the catalytic converter does not help reduce the greenhouse effect.
The primary mechanism by which CO2 contributes to global warming is by what?
The sun's light and heat (in all the visible frequencies) warms the surface of the earth. The earth then emits heat in the form of lower-frequency infra-red rays which can be trapped by the carbon dioxide (CO2) and other greenhouse gases in the atmosphere.
Does Co2 have a sent Just Co2 Nothing else just plain Co2?
no. CO2 is an odorless, tasteless gas question is like does co2 has odor. and co2 is plan chemical. co2 is as said odorless chemical compound. but it is very dangerous to earth as it absorb the infrared and near infrared radiation which hea the earth. this is one of the major green house gas.
What gas absorb and trap heat radiation?
Collectively the gases in the Earth's atmosphere which trap heat are called the Greenhouse Gases (GHGs). They are prmarily:Water vapour (H2O)Carbon dioxide (CO2)Methane (CH4)Nitrous oxide (N2O)Ozone (O3)Chlorofluorocarbons (CFCs)
What gases such as co2 and water vapor absord the sun radiation and reflect it back to earth's surface?
Greenhouse gases.
The ozon layer has partitially been destoryed cooling. However there is a lot of CO2 in the atmosphere heating. Shouldn't we reach an equilibrium Is there a connection between the two effects?
well, the ozone layer being depleted does not cool off the atmosphere. Quite the opposite actually. The ozone layer protects the earth from harmful radiation from the sun. Radiation such as UV radiation that contributes to: sunburns, skin cancer, and heating of the atmosphere and ground. Carbon Dioxide CO2 does heat the atmosphere like you said due to it's greenhouse effect. This effect occurs when radiated heat from earth tries to escape into space, but is stopped and reflected back by a barrier of CO2 (similar to what happens in a greenhouse with the glass being like CO2). So your answer is NO. Those two effects cannot cancel each other out.
What blocks ultra violate radiation?
the ozone layer but because of CO2 the are some gapes in it that can effect the earth and destroy the planet
Is nitrogen a good or bad absorber of incoming solar radiation?
Yes, it absorbs solar radiation in the form of infrared rays rising from the surface of the earth. This heat is absorbed by the greenhouse gases (carbon dioxide (CO2) and methane (CH4)) and this is causing global warming.
Why do rising co2 levels concern some scentist?
They theorise that the co2 levels will hinder the escape of heat radiated by the earth leading to global warming
Can earth be cooled by deforestation?
No, but reforestation can cool the earth. Trees absorb Co2, they use the Carbon to grow and expell oxygen. By removing Co2 the atmosphere will absorb less heat and thus cool the planet.
What happens to the radiation that earth reemits?
It can go out to space, or it can be trapped by various gases in the atmosphere, i.e., greenhouse gases such as CO2 and water vapor.
