A* Summary notes with for 3.6.2.2 Ideal gases , A level Physics.

Ideal Gases
0 K = -273.15°C (The lowest possible temperature a substance
can reach, when its molecules have zero kinetic energy)

To convert from degrees Celsius to Kelvin you should add
273.15.

, Gas Laws


Boyles Law

At a constant temperature, the pressure of an
ideal gas is inversely proportional to the volume
of a gas.

P = Pressure (Pa)
P ∝ 1/V
V = Volume (m^3)


Charles’s Law

At a constant pressure, the volume of an ideal gas
is proportional to the temperature of the gas.

V = Volume (m^3)
V ∝T
T = Temperature (K)


Pressure Law

At a constant volume, the pressure of an ideal gas
is proportional to the temperature of the gas.

P = Pressure (Pa)
P ∝T
T = Temperature (k)
