THERMAL Flashcards
1
Q
What is a mole.
A
a substance which contains 6.02x10^23 particles
2
Q
is Na has a ram of 23, how many grams of Na will be in one mole?
A
23
3
Q
link the equation containing, n, NA, N
A
N=nNA
NA=number of particles
n=moles
N=number of mols substance will contain
4
Q
in what scenario would we use pV=NkT, instead of pV=nRT
A
we use NkT when we have number of molecules instead of moles
5
Q
Do we use Kelvins or Celcius for pV=nRT and pV=NkT
A
kelvins
6
Q
how do you convert from celcius to kelvins
A
add 273
7
Q
what is R, (Gas constant)
A
8.31 J/mol K
8
Q
define specific heat capacity
A
the energy required to raise the temperature of 1kg of a substance by 1 degrees
9
Q
what is specific latent heat
A
the energy required to melt/vapourise 1kg of a substance.
