If methane at a pressure of 3.2 atm and at 21 °C is introduced into a container, the gas be heated to ______°C to increase the pressure to 12 atm.

Answer 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

Answer 2

i got 352 is that right

Answer 3

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

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

Answer 4

i got 831 i don't think this is right???

Answer 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?
