Loren has the samples of elements that are listed below at room temperature. He exposes the samples to the same heat source until each sample reaches a temperature of 90.0°C.

10 g of Al(s) (C subscript p. = 0.897 J/(gi°C))
10 g of Ag(s) (C subscript p.= 0.234 J/gi°C )
10 g of Fe(s) (C subscript p. = 0.450 J/gi°C)
10 g of Zn(s) (C subscript p. = 0.387 J/gi°C )

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
