Question

Which gas law has the assumptions of a fixed amount and pressure of a gas

Answer 1

Charles Law as (T1/V1)=(T2/V2) is the equation assuming pressure is constant and the amount of moles is constant

Answer 2

Answer: The correct answer is Charles' Law.

Step-by-step 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).

`P\propto (1)/(V)` (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).

`V\propto T` (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).

`P\propto T` (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.

`V\propto n` (At constant temperature and pressure)

From the above information, it is visible that the law which has fixed amount and pressure is Charles' Law.
