If the barometric reading is at 28.09 in what kind of weather do you predict they may have?

In general, a falling barometer indicates the approach of a storm. If the mercury is over 30.20 inches but falling quickly, warmer, cloudier weather is coming. If the mercury continues to fall, the weather will worsen. When the mercury level is between 30.20 and 29.80 inches and dropping rapidly, expect precipitation.

Explanation:

idek warm?

Explanation:

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
