The diagram below shows how heat can be transferred in the atmosphere as hot air rises and cool air sinks. When the hot, wet air rises, a large, anvil-shaped cloud can form and produce heavy rain. Image courtesy of Robert Simmon, NASA

The type of heat transfer that causes the air to circulate and form such clouds is called .
A.
conduction
B.
radiation
C.
evaporation
D.
convection

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.
