Answer 2

Answer:

The correct answer is the amount of gas or number of moles of gas.

Explanation:

Boyle s law:

Boyle's law describes that at constant temperature and amount of gas, the pressure and volume of gas are inversely proportional to each other.

Charles's law:

It described that at constant pressure and number of moles of gas, the temperature and volume of gas are directly proportional to each other.

Gay-Lussac's law:

According to this law at constant volume and amount of gas, the temperature and pressure are directly proportional.

Hence according to above described 3 laws, the moles or mount of gas remains constant.
