1. Temperature and Pressure are proportional. If you increase the temperature, the pressure will increase.

P1/T1 = P2/T2

Temperature has to be in Kelvin

C + 273 = K

3. I got something different:
3.2/294 = 12/K

That gives us the Kelvin temp then subtract 273 to get C.

5. K=C+273
=21+273
=294k

P1/T1=P2/T1

3.3/294=12/T1

T1=1102.5k
Therefore need to be increased by 829.5 degrees Celsius.
Is this correct?
