Methane by Samantha Tabatabai https://padlet.com/4000550/3ogx4ey64stizbzn By: Samantha Tabatabai en-us 2020-12-17 12:26:39 UTC 2023-05-17 01:59:08 UTC hello@padlet.com WHY WE SHOULD CARE ABOUT IT 4000550 https://padlet.com/4000550/3ogx4ey64stizbzn/wish/1027462451 We should care about Methane because we are producing too much which is rising sea levels and warming our planet. Since methane is a powerful greenhouse gas, around 30 times more potent than carbon dioxide, researchers fear that methanein large enough quantities in the atmosphere could accelerate global warming.If methane leaks into the air before being used from a leaky pipe, for instance  it absorbs the sun's heat, warming the atmosphere. For this reason, it's considered a greenhouse gas, like carbon dioxide.]]> 2020-12-17 12:26:39 UTC https://padlet.com/4000550/3ogx4ey64stizbzn/wish/1027462451 GLOBAL WARMING POTENTIAL (GWP VALUE) 4000550 https://padlet.com/4000550/3ogx4ey64stizbzn/wish/1027462454 Methane (CH4) is estimated to have a GWP of 28–36 over 100 years]]> 2020-12-17 12:26:39 UTC https://padlet.com/4000550/3ogx4ey64stizbzn/wish/1027462454 REFERENCE SOURCES FOR INFORMATION 4000550 https://padlet.com/4000550/3ogx4ey64stizbzn/wish/1027462455 “Overview of Greenhouse Gases.” EPA, Environmental Protection Agency, 8 Sept. 2020, www.epa.gov/ghgemissions/overview-greenhouse-gases.

About 60% of global methane emissions are due to human activities. Methane also was responsible for about 23% of climate change in the 20th century. Methane is produced under conditions where little to no oxygen is available]]> 2020-12-17 12:26:39 UTC https://padlet.com/4000550/3ogx4ey64stizbzn/wish/1027462458 PERSISTENCE IN THE ATMOSPHERE 4000550 https://padlet.com/4000550/3ogx4ey64stizbzn/wish/1027462459 Methane in the Earth's atmosphere is a strong greenhouse gas but methane is not as persistent a gas as CO2. Methane has a global warming potential (GWP) 84 times greater than CO2 in a 20-year time frame]]> 2020-12-17 12:26:39 UTC https://padlet.com/4000550/3ogx4ey64stizbzn/wish/1027462459 PRODUCERS (How it gets into the atmosphere): 4000550 https://padlet.com/4000550/3ogx4ey64stizbzn/wish/1027462461 In nature, methane is produced by the anaerobic bacterial decomposition of vegetable matter under water . Wetlands are the major natural source of methane produced in this way. Methane is emitted to the atmosphere during the production, processing, storage, transmission, and distribution of natural gas. Also through the production, refinement, transportation, and storage of crude oil. ]]> 2020-12-17 12:26:39 UTC https://padlet.com/4000550/3ogx4ey64stizbzn/wish/1027462461 ITS CHEMICAL PROPERTIES 4000550 https://padlet.com/4000550/3ogx4ey64stizbzn/wish/1027462462 Methane is lighter than air, having a specific gravity of 0.554.The boiling point of methane is −162 °C (−259.6 °F) and the melting point is −182.5 °C (−296.5 °F).]]> 2020-12-17 12:26:39 UTC https://padlet.com/4000550/3ogx4ey64stizbzn/wish/1027462462 ITS PHYSICAL PROPERTIES 4000550 https://padlet.com/4000550/3ogx4ey64stizbzn/wish/1027462464 Molecular weight: 16.043 Critical temperature:190.55 K
