Answer The correct answer is Combined gas law.
Step-by-step explanation:
1) Charles's law states that volume occupied by the gas is directly proportional to the temperature in Kelvins when pressure is kept constant.
(at constant Pressure)
In summers, temperature increases with which volume occupied by the gas also increases in accordance to Charles law.
2) Boyle's law states that pressure of the gas is inversely proportional to the volume occupied by the gases at constant temperature.
(at constant Temperature)
3) Gay Lussac's law states at constant volume the pressure exerted by the gas is directly proportional to the temperature Kelvins.
(at constant volume)
4) Avogadro law states that for a given mass of an ideal gas , the volume occupied by the gas is directly proportional to the moles of the gas under constant pressure and temperature.
(at constant pressure and temperature)
On combining all these laws, we get Combined gas law::
PV=nRT
Hence, the correct answer is 'The combined gas law'.
