The air density at mount Everest is less than that at the sea level . It is found by mountainers that for one trip lasting few hours , the extra oxygen needed by them corresponds to 30000 cc at sea level (pressure 1 atm , temperature `27^(@)C` ). Assuming that the temperature around Mount Everested is `-73^(@)C` and that the pressure at which oxygen be filled (at site) in the cylinder isA. 3.86 atmB. 5.00 atmC. 5.77atmD. 1 atm |

Answer» Correct Answer - A Here, `p_(1)=1"atm",T_(1)=300K.V_(1)=30000cc=30L` `and" " T_(2)=200K,V_(2)=5.2L` `therefore" " p_(2)=(p_(1)V_(1)T_(2))/(T_(1)V_(1))=(1xx30xx200)/(300xx5.2)=3.86"atm` |
