A gas initially at 30C must be changed to ? C to triple the pressure.

I think Bob Pursley answered this question either early this a.m. or yesterday. My answer is not the same method but it will work also.
Use PV = nRT
You can assume V, n, and you know R. Plug in T for 30 degrees C but change to Kelvin first.
Now use the same V and n, triple the pressure you initially used, and calculate the new T. Convert Kelvin, then, to C. Post your work if you get stuck.
