Combining boyles law and Charles law to get general gas equation

The general gas equation can be obtained by combining Boyle's Law and Charles's Law, as well as Avogadro's Law. These three gas laws can be written as:

Boyle's Law: PV = k (constant at constant temperature)
Charles's Law: V/T = k (constant at constant pressure)
Avogadro's Law: V/n = k (constant at constant temperature and pressure)

Combining these three equations, we can derive the general gas equation:

(PV)/T = nR

where:
P = pressure of the gas
V = volume of the gas
T = temperature of the gas
n = amount of gas (in moles)
R = ideal gas constant

This equation is known as the ideal gas law, which describes the behavior of gases under certain conditions.
