CHOKING HAZARD -- Small parts. Not for children under 3 yrs.
A set of equipment permitting quick and easy experiments to demonstrate the effect of greenhouse gases on the absorption of infra-red radiation. Solar radiation received by the earth is simulated here by means of short-wave infrared radiation that is attenuated by absorption in water and visible light from a reflector lamp. Infra-red radiation emitted by the earth is simulated by heating a black metal disc. Both types of radiation are made to pass through air or butane gas in a metal tube and subsequently registered with a thermopile. Comparison of the obtained values reveals that long-wave infra-red radiation is absorbed to a high degree by butane gas. Consequently butane gas released into the atmosphere causes it to heat up, butane gas is a greenhouse gas. Content includes: 1 base plate, 1 lamp holder with reflector lamp, 1 cuvette on stem, 1 black metal disc, 1 metal tube, simple, 1 metal tube, with taps, 2 mounting stems, 1 silicone hose, 1 storage case.
