Gas is heated from 480. k to 750. k and the pressure is kept constant, what final volume would result if the original volume was 267 l?

Charles law gives the relationship between volume and temperature of gas.
It states that at constant pressure volume is directly proportional to temperature
Therefore
V/ T = k
Where V - volume T - temperature in kelvin and k - constant
V1/T1 = V2/T2
Parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation
Substituting the values in the equation
267 L/ 480 K = V / 750 K
V = 417 L
Final volume is 417 L

What does that mean you dum bum

Ithink is a because if say increased in electronegativity
