What is the ideal gas equation?
pV = nRT
2
New cards
What is p, it's units and it's rearrangement?
p= pressure in pascals (pa)
p= nRT/V
p= nRT/V

New cards
What is V, it's unitsand it's rearrangement?
V= volume in metres cubed
decimetre cubed - metre cubed = divide by 1000
centimetre cubed - metre cubed = divide by 1000000
V= nRT/p
decimetre cubed - metre cubed = divide by 1000
centimetre cubed - metre cubed = divide by 1000000
V= nRT/p

New cards
What is n, it's units and it's rearrangement?
n= moles in moles
n= pV/RT
moles= mass/Mr
n= pV/RT
moles= mass/Mr

New cards
What is R, it's units and it's rearrangement?
R= the gas constant, in JK-1mol-1
ALWAYS 8.31
ALWAYS 8.31

New cards
What is T, it's units and it's rearrangements?
T= temperature in kelvins (K)
0 K= -273 degrees celsius
T= pV/nR
0 K= -273 degrees celsius
T= pV/nR
