Does glass absorb heat?

Question

I'm going to make a model of global warming and i need something to represent the green house effect.....

Answer 1

Not very well.  IN the winter time try touching the glass windows while inside a warmed room.  The glass will be cold to the touch.  The effect is more so if it is not a double paned window where the air between the glass panes tends to help keep the inner pane relatively warm.  Of course direct heat will be trapped by glass but it will not hold it for long.

Glass works in greenhouses because it is transparent to light, it lets the light through to heat up the interior of the green house.  And because it is not a good conductor of heat, the heat is trapped inside. Again, try it on a cold day.  The temperature of a pane of glass is closer to the temperature of the colder side of the glass.

Bubble wrap would make a good heat trap for a global warming model.  Most of the light will pass through, the air bubbles trapped in the bubble wrap makes a very good insulation.

Answer 2

glass both transmits and absorbs. wen sunlight hits glass, some light is transmitted and the rest is absorbed.

Answer 3

Glass transmitts visible light.  If the transmitted light is absorbed by something dark (like dirt) then the dirt will heat up.  The dirt radiates BUT it does so at long wavelengths in the infarred (IR).  The glass will not transmit that IR energy but will absorb it.  The glass will reradiate in back into the dirt increasing the temperature of the dirt.
