do we need to know any other formulae apart from the ones on
http://www.gosford-hill.oxon.sch.uk/...lp/learnAS.doc

and the formulae booklet provided?
or are things like standing waves in pipes surplus to requirements?

much appreciated :smile:

On one of thoses lists (learnA2 gosford-hill) there is the equation pV=nRT ... and it says T is measured in degrees celcius, where I was under the impression T was measured in kelvin...

unfortunately I'm not doing so well in physics despite being predicted an A, if anyone has any revision tips I'd sure like to hear them. :smile:

i think the formula will work in degrees or kelvin.

:eek: Definately not. Must be in Kelvin.

Hello, the second link seems to have expired, don't suppose you have another (or the same) need to know fact sheet? please!:colondollar:

I don't know if you still need this but it's disappeared completely off of the website. I'd try the Gosford ones, they cover everything.
Thanks for the links. :biggrin:

It doesn't matter if it is in celsius or kelvin as T is change in temperature and celsius and kelvin both go up by the same amount so adding 1 degree kelvin to the temperature is the same as adding 1 degree celsius.
thanks author for a nice post
