Convert 1365.4 joules into kilocalories.

0.326338 kcal

Explanation:

Data given:

Value in Joules = 1365.4 joules

Value in Kilocalories (kcal) =  to find

Solution:

Joule and Kilocalori both are the unit of energy

Relation of kilocalori

                   1 joule = 0.000239 kcal

so now to find

1365.4 joules equals to how much kilocalories

if

                                 1 joule = 0.000239 kcal

then                1365.4 joules = ? Kilocalories

by cross multiplication

          1 joule x ? Kilocalories = 0.000239 kcal x 1365.4 joules

By rearranging

           Kilocalories = 0.000239 kcal x 1365.4 joules / 1 joule

         Kilocalories = 0.000239 kcal x 1365.4 joules / 1 joule

         Kilocalories = 0.32633 kcal

So

         1365.4 joules = 0.32633 kcal  

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
