When looking up at the clouds, you can usually make out different shapes and figures with cumulus clouds stratus clouds cirrus clouds altostratus clouds

desert climates can have very hot days and very cold nights. this is because there is usually cloud coverage there is usually a clear sky there is usually precipitation there is usually hot or cold wind

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
