solmaris [256]
Graph D.

Charles's law states that at the same pressure, the Volumen of a gas is proportional to its temperature (absolute temperature).

This is

V = K T, where K is the constant of proportionallity.

You can also write it in the form

V1 / V2 = T1/ Ts

When Temperature rise Volumen rise in a proportional way. If Temperature doubles Volumen doubles, if Tempearature is decreases to on third, Volume will decrease to one third.
