The combined gas law is
a gas law that combines
Charles's law, Boyle's law,
and Gay-Lussac's law
Charles's law states that volume
and temperature are directly
proportional to each other as long
as pressure is held constant
Boyle's law asserts that
pressure and volume are
inversely proportional to each
other at fixed temperature
Gay-Lussac's law introduces a
direct proportionality between
temperature and pressure as
long as it is at a constant volume
Boyle's Law
Multiply by Charles Law
Multiply by Gay-Lussac's Law
The ratio between the pressure-volume product
and the temperature of a system remains constant.
This can be stated mathematically as
Application of the combined gas law can be used to explain the
mechanics where pressure, temperature, and volume are affected.
For examples air conditioners, refrigerators and the formation of
clouds.and also use in fluid mechanics and thermodynamics.
