Calcium chloride is added to the roadways after a snowstorm. Which colligative property is being showcased here?

A) osmotic pressure
B) boiling point elevation
C) vapor pressure lowering
D) freezing point depression

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
