Combined Gas Law
Combined Gas Law is basically Boyle's, Charles', and Gay-Lussac's Gas Law combined into one. The rules are the same, you must convert Celsius to Kelvin and make sure your units match up!
The formula for combined gas law is P1(V1)=P2(V2) , remeber sig figs!
T1 T2
Ex. The sample of gas took up 35.0L of space at 124 degree Celsius and 84.56 kPa. If the pressure changed to 4.56 atm and the temperature increased by 16, what would the new volume be?
P1 - 84.56 kPa 4.56atm x 101.324 psi = 462 psi
V1 - 35.0L 1 atm
T1 - 273 + 124 = 379 K 84.56(35.0) = 462(V2) 1222314.8 = 183414x X = 6.66L
P2 - 462 psi 373 = 413 183414 = 183414
V2 - ?
T2 - 273 + 140 = 413 K
