Answer:
5 atm
Explanation:
Gay-Lussac's Law states that pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature.
P1 / T1 = P2 / T2
Plug the information given in and you get
(10atm)(10 K)=(P2)(20K)
Divide both sides by 20 K and you get the unknown pressure which is 5 atm.
