Liquid water can be separated into hydrogen gas and oxygen gas through electrolysis. The hydrogen and oxygen gases, H2 and O2, produced from 1 mole of liquid water are collected in 10 L containers at 1 atm. Will the temperatures of the gases be equal?
In one to two sentences, use the ideal gas law to explain your answer. (2 points)

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.

it is the most commonly accepted one
