BHOPAL GAS TRAGEDY At 11.00 PM on December 2 1984‚ while most of the one million residents of Bhopal slept‚ an operator at the plant noticed a small leak of methyl isocyanate (MIC) gas and increasing pressure inside a storage tank. The vent-gas scrubber‚ a safety device designer to neutralize toxic discharge from the MIC system‚ had been turned off three weeks prior . Apparently a faulty valve had allowed one ton of water for cleaning internal pipes to mix with forty tons of MIC. A 30 ton refrigeration

“THE GAS MAN COMETH” The documentary‚ “Gas Land”‚ by Josh Fox‚ is a film about the problems with contaminated groundwater due to excessive and unregulated natural gas extraction across the country. In the film‚ Fox travels all over to talk to many people who have rented out their land to natural gas companies‚ only to get contaminated water and no help from any company or organization with the problems that ensue. Fox uses many techniques in his film to get across his point that America should

Pak-Iran gas pipeline Pak-Iran gas pipeline project - which would essentially change the face of the ongoing energy crisis in Pakistan for the foreseeable future – seems to be ending in despair. Initially‚ the project too included India. However‚ India dropped out along the way since the negotiations commenced nearly two decades ago. Now‚ there are again reports doing round in media‚ reporting Indian Minister of External Affairs Salman Khurshid‚ that India might renter negotiations over the IP gas pipeline

Ideal Gas Law: The ideal gas law is the equation of state of a hypothetical ideal gas. It obeys Boyle’s Law and Charles Law. Ideal Gas Law Formula : General Gas Equation: PV = nRT Pressure(P) = nRT / V Volume(V) = nRT / P Temperature(T) = PV / nR Moles of Gas(n) = PV / RT where‚ P = pressure‚ V = volume‚ n = moles of gas‚ T = temperature‚ R = 8.314 J K-1 mol-1‚ ideal gas constant. Ideal Gas Law Example: Case 1: Find the volume from the 0.250 moles gas at 200kpa and 300K temperature

their gills only allow them to take in oxygen from the water. The percentage of oxygen is the water is significantly lower than the amount of oxygen in the air. Fish have adapted to be able to filter oxygen from the water despite its low percentage. Gas exchange in fish occurs in their gills which is supported by a bony arch. Fish take water in through their mouths. Water enters via a fish’s open mouth‚ its opercula close and stop water from leaving before being forced through the gill filaments. Once

Ferry is considered upper basin and south is lower. It is the lower basin states (Arizona‚ California‚ Nevada‚ New Mexico‚ and Utah) that are experience the brunt of the water shortage. Climate change in the southwestern US includes above averagetemperatures‚ and less rainfalls. These changes are contributors to the water shortage. GeoscientistBrad Udall‚ director of the University of Colorado Western Water Assessment‚ estimates the climate change will contributeto 5-20 percent of water loss in the
