Question

If a gas sample has a pressure of 30.1 kPa at 0.00C, by how many degrees Celsius does the temperature have to increase to cause the pressure to double?

Answer 1

Use P1/T1 = P2/T2

P1 = 30.1
T1 = 0.00 = 273.15 K
P2 = 60.2
T2 = ? in kelvin
If you want T in C, then 273 + C = K. Substitute and solve for C.
