wht do u mean?? ???
Shazizzzle:
Umm, is it necessary to use the absolute temperature, i.e Kelvin, when using the gas laws?
Because, in many of the past papers, we do not covert the temp. from deg. C to deg. K. Do we have to?
Some books say the only correct answer is obtained using K.
But, isn't that just the same thing? :S
i.e K = 273 + C

The volume of a fixed mass of gas id directly proportional to its absolute temperature if the pressure is kept constant
V/T = K
Pressure Law
The pressure of a fixed mass of gas is directly propotional to its absolute temperature if the volume is kept constant
p/T = K
Boyle's Law
You should have someone calling you MR HELPFUL xD
Thanks Vin for helping us all (:
For a fixed mass of gas at constant tmeperature
pV = K
combining the laws
p1V1 p2V2
------ = -----
T1 T2

actualy in pastpapers u hd 2 do tht !!
Ivo:
OK, super hard question for Q10) If someone can guide me through how to work out b) onwards, that would be most helpful.
This is same paper, w09.
