{"product_id":"greenhouse-effect-experimental-set","title":"Greenhouse Effect –\nExperimental Set","description":"\u003cbr\u003eProduct Information: ..\u003cbr\u003eA set of equipment permitting quick and easy experiments to demonstrate the effect of greenhouse gases on the absorption of infra-red radiation.\u003cbr\u003eSolar 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, i.e. butane gas is a greenhouse gas.","brand":"3B Scientific","offers":[{"title":"Default Title","offer_id":49419055366421,"sku":"3BS1000837","price":882.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0857\/4897\/3845\/files\/U8460500-230_01_1200_1200_Greenhouse-Effect-Experimental-Set.jpg?v=1761021194","url":"https:\/\/unitedsupplycorp.com\/products\/greenhouse-effect-experimental-set","provider":"United Supply Corp.","version":"1.0","type":"link"}
