![What is the depth of the ocean layer
(per unit area) with the same total
heat capacity as the entire
atmospheric column?
[it helps to first identify the mass
(per unit area) of the atmosphere,
which can be easily ascertained by
thinking of the average surface
pressure as resulting from the
weight of all the air in the entire
atmospheric column above].
The total column mass of water
(vapor+liquid) in the atmosphere is
observed to be, on average, about
20 kg m² (99.5% of which is in the
gas phase)
Average molecular weight of dry air:
