```							Let P2 = 1.004 P1 ..... A 0.4% increase in P Let T2 = T1 + 1 ........... See note below P1V1/T1 = P2V2/T2 ..... combined gas law P1/T1 = P2/T2 ............... Assume V remains constant. T1 = P1T2 / P2 .............. solve for T1 T1 = P1(T1+1) / (1.004P1) T1 = (T1+1) / 1.004 1.004T1 = T1 + 1 1.004T1 - T1 = 1 0.004T1 = 1 T1 = 1 / 0.004 T1 = 250K Note: A 1 degree increase on the Celsius scale is a 1 degree increase on the Kelvin scale. Temperatures used in the combined gas law must be in Kelvin.
