Pls try to write the 3 facts (answers) shortly and plz don’t miss doing what the role or function is of the eyes (do it shortly like again). This is due today according to my science teacher, thank you so much and god bless all of you :) *spam* ? *may b* have a amazing day!!!

the increase of protons   hope this

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.
