What is the law of conservation in chemistry

The Law of Conservation of Energy states that The total energy of an isolated system is constant. Energy can neither be created nor destroyed. It can only be transformed from one form to another or transferred from one system to another.

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

d) a person who learns about the world by observing it.

explanation:

scientist are people who discover why and how things are done and made in the world.
