Question

is pressure directily or inversely proportional to temp.?

Answer 1

Gay-Lussac's Law: The Pressure Temperature Law. This law states that the pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature. As the pressure goes up, thetemperature also goes up, and vice-versa.

It is a law....and that is why i am saying that P is diectly proportional to T.
