Question #2512
How is heat energy trapped in a greenhouse?
Expert's answer
Objects heated
by sunlight emit infrared radiation. These objects then emit infrared radiation that is absorbed or reflected by the glass
roof, thus trapping the thermal energy in the greenhouse instead of letting it escape.
