18a) Crtate Charler law. vtater that the volume of a given mar of a gak is directly proportional to its abrolute temperature at a constant prossure. b The volume of a sample of ndrogen gas at a tomperatu of agik and 1.0 times 10^5 Parale was 3.5 times 10^-2 mathrm(~m)^3 . Calculato the temperature at which the volume of legan would be 2.5 times 10^-2 mathrm(~m)^3 at 1.0 times 105 Pascaln

To solve this problem, we can use Charles's Law, which states that the volume of a given mass of a gas is directly proportional to its absolute temperature at constant pressure. Mathematically, this can be expressed as: where:- is the initial volume- is the initial temperature- is the final volume- is the final temperatureGiven:- - (assuming the initial temperature is 300 K)- - (constant pressure)We need to find .Using Charles's Law: Rearranging to solve for : Substituting the given values: Therefore, the temperature at which the volume of the gas would be at is approximately .
