Which of the following is an example of a true scientific theory a) if a woman has a heart burn during pregnancy her baby will be born with a lot of hair b) throwing a pinch of salt over your shoulder is good luck c) if you break a mirror you will have 7 years of bad luck d) sterilizing equipment prevent contamination

if you're asking what comes out, it's steam.

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
