laws which govern the behaviour of a perfect gas due to the
variation in its pressure, temperature and volume are known
as gas laws.
are three basic gas laws.
It states that when the temperature is remains constant; the
volume of a perfect is inversely proportional to its
absolute pressure. i.e.
V α 1/P
(T is constant)
Or PV =
= P2V2 (when a gas changes its state
from 1 to 2 at constant temperature)
The volume of a perfect gas is directly proportional to its
absolute temperature, if the pressure remains constant. i.e.
V α T
= V2/T2 (when a gas changes its state
from 1 to 2 at constant pressure)
The pressure of the gas is directly proportional to its
temperature if the volume remains constant. i.e.
P α T
or P/T = Constant
= P2/T2 (when a gas changes its state
from 1 to 2 at constant volume)
