Which gas law has the assumptions of a fixed amount and pressure of a gas?

Avogadro's law 

Boyle's law 

Charles's law 

Gay-Lussac's law

***[isuru]*** · Answer

charles law..
    The volume of a given mass of an ideal gas is directly proportional to its temperature on the absolute temperature scale (in Kelvin) if pressure and the amount of gas remain constant; that is, the volume of the gas increases or decreases by the same factor as its temperature
so...
    they assume that the amount of gas is fixed and so is the pressure...

hope this will help ya.. :)
