According to Charles's law, under which conditions will the volume of a given amount of gas be proportional to temperature? when pressure and the number of moles increase when pressure and the number of moles decrease when pressure and the number of moles remain constant when the atmospheric pressure is 1.019 atm

Respuesta :

Charles law states that volume is directly proportional to temperature,
when pressure and number of moles remain constant.
This is because both pressure and number of moles of gas affect the parameters temperature and volume. therefore if pressure and number of moles change then the relationship between volume and temperature changes as well
correct answer is 
when pressure and the number of moles remain constant

Answer:  when pressure and the number of moles remain constant

Explanation:

Charles' Law: This law states that volume is directly proportional to the temperature of the gas at constant pressure and number of moles.

[tex]V\propto T[/tex]     (At constant pressure and number of moles)

[tex]{V_1\times T_1}={V_2\times T_2}[/tex]

where,

[tex]V_1[/tex] = initial volume of gas

[tex]V_2[/tex] = final volume of gas

[tex]T_1[/tex] = initial temperature of gas

[tex]T_2[/tex] = final temperature of gas

Therefore, the volume of gas is proportional to temperature when pressure and number of moles are constant.
