Charles’ law can be represented as?
V
1
/ T
1
= V
2
/ T
2
V/T = constant
V ∝ T at constant P
All of the above
What happens at S.T.P?
Molar volume is 22.4 dm3 or 22.4 litres
P = 1 atm or 760 mmHg or 101325 Pa
T = 0
o
C or 273.15 K
All of the above

o
C, if the pressure is kept constant?
116 dm³
161 cm³
161
161 cm³
The number of moles (n) of a gas at S.T.P. or R.T.P. is calculated by which formula?
V

PV = nRT
n = V / V
m
Where V = given volume and V
m
= molar volume
__ states that the volume occupied by a fixed amount of gas is directly proportional to its absolute (Kelvin) temperature at constant pressure
