(match each instrument with its description)

1. weather maps/satellite
2. doppler radar
3. radiosonde
4. wind vane
5. psychrometer

a. uses two thermometers; a dry and wet bulb
b. points in the direction winds are coming from
c. uses frequency waves to track particle movement
d. used to track air masses and fronts
e. carried with a weather balloon

Match each weather instrument with its description.

a:

by the combination of an unlimited number of elements

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.
