    The air density at Mount Everest is less than that at the sea level. It is found by mountaineers that for one trip lasting a few hours, the extra oxygen needed by them corresponds to $30,000\ cc$ at sea level (pressure $1$ atmosphere, temperature $27^oC).$ Assuming that the temperature around Mount Everest is $-73^oC$ and that the oxygen cylinder has capacity of $5.2\ litre,$ the pressure at which $O_2$ be filled (at site) in cylinder is ..... $atm$
