Air in a closed cylinder is heated from 25 degree to 36 degree. If the initial pressure is 3.80 atm what is the final pressure?

Aww man, I love these types of problems!

So, it's a simple formula:

P1*V1/T1=P2*V2/T2

In this case, we remove V (volume) as there is none listed, leaving this:

P1/T1=P2=T2

Think you got it from here? All you gotta do is plug in the numbers and solve

If you have any further problems, just let me know!
