All the oxygen gas from a 10.0 l container at a pressure of 202 kpa is added to a 20.0 l container of hydrogen at a pressure of 505 kpa. after the transfer, what are the partial pressure of oxygen and hydrogen?

i wish i could but this one is weird give me abc and i can solve it.

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
