Its mixing a ratio in the atmosphere is lower than that of CO2.]]> 2020-11-16 19:28:35 UTC https://padlet.com/4000366/kyvs2w0djtl6fi7o/wish/928909067 PERSISTENCE IN THE ATMOSPHERE 4000366 https://padlet.com/4000366/kyvs2w0djtl6fi7o/wish/928909070 Sulfer Hexafluoride is not considered likley to harm the environment in the vicinity of its release. On a global scale however it is a greenhouse gas contributing to global warming. It has an exremely high global warming potential, but does not contribute particularly significantly to global warming because of the small amounts released. It can persist in the atmosphere for up to thousands of years.]]> 2020-11-16 19:28:35 UTC https://padlet.com/4000366/kyvs2w0djtl6fi7o/wish/928909070 PRODUCERS (How it gets into the atmosphere): 4000366 https://padlet.com/4000366/kyvs2w0djtl6fi7o/wish/928909074 Releases of sulfur hexafluoride occur from electrical substations, magnesium smelters and from some pther consumer goods. There are no natural gases released into the environment. ]]> 2020-11-16 19:28:35 UTC https://padlet.com/4000366/kyvs2w0djtl6fi7o/wish/928909074 ITS PHYSICAL AND CHEMICAL PROPERTIES 4000366 https://padlet.com/4000366/kyvs2w0djtl6fi7o/wish/928909080 Sulfur Hexafluoride melts at - 50.5 C and sublimes at - 63.9 C, critical pressure 3.759 mpa (37.2 atm), critical temp. , 45.55 C, liquid density 1.336 g/cm3, dielectric constanr 1.00204 (gas), 1.81 (liquid)]]> 2020-11-16 19:28:35 UTC https://padlet.com/4000366/kyvs2w0djtl6fi7o/wish/928909080 MOLECULE STRUCTURE & SHAPE 4000366 https://padlet.com/4000366/kyvs2w0djtl6fi7o/wish/928909083 2020-11-16 19:28:35 UTC https://padlet.com/4000366/kyvs2w0djtl6fi7o/wish/928909083 MOLECULE DESCRIPTION 4000366 https://padlet.com/4000366/kyvs2w0djtl6fi7o/wish/928909085 Name: Sulfur Hexafloride
