Answer: The correct answer is Charles' Law.
Explanation:
The ideal gas is derived from gas laws:
1. ) Boyle's Law: This law states that pressure is inversely proportional to the volume of the gas held at constant temperature and number of moles (amount of gas).
[tex]P\propto \frac{1}{V}[/tex] (At constant temperature and amount)
2) Charles' Law: This law states that volume is directly proportional to the temperature of the gas at constant pressure and number of moles (amount of gas).
[tex]V\propto T[/tex] (At constant pressure and amount)
3) Gay-Lussac's Law: This law states that pressure is directly proportional to the temperature of the gas at constant volume and number of moles. (amount of gas).
[tex]P\propto T[/tex] (At constant volume and amount)
4) Avogadro's Law: This law states that volume is directly proportional to the number of moles (amount of gas) of the gas at constant pressure and temperature.
[tex]V\propto n[/tex] (At constant temperature and pressure)
From the above information, it is visible that the law which has fixed amount and pressure is Charles' Law.
