Which of the following conditions remain constant in gay-lussac's law? temperature and number of moles volume and number of moles density and temperature volume and pressure

Volume and number of moles.

Explanation:

Gay-Lussac's law was found by Joseph Louis Gay-Lussac in 1808. It states that, for a given mass (no. of moles) and constant volume of an ideal gas, the pressure exerted on the sides of its container is directly proportional to its absolute temperature.

So, no. of moles and V are constant.

P ∝ T,

∴ P1/T1 = P2/T2.

So, the right choice is: Volume and number of moles.

Ithink 2 is the correct

While unproven, it uses facts to support part of a conclusion. it is still factual and has predictive power, however.
