The deepest point in the ocean is 11km below sea level, deeper than Mt. Everest is tall.What is the pressure in atmospheres at this depth?

1 answer

pressure= atm pressure+ pressure pgh

pressure due to height= pgh= 1000kg/m3 *9.8m/s* 11000m = 107800kPa
1atm=101.3Kpa so 107800kPa=1064.16 atm

total pressure= 1+1064.16atm
=1065 atm.
=rounding to two sig fig: 1100atm
