Beryllium is a rare metal that is gray in color,
strong, and lightweight. the following data was
obtained from a calorimeter experiment:
cmetal = -
m eryllium = 10.1 g
mwater = 38.8 g
• at beryllium = final t - initial t
= 27.7°c - 100°c
* at water = final t - initial t
= 28.4°c – 20.2°c
• cwater = 4.18 j/gºc
the specific heat of beryllium is
ecific heat of beryllium is
j/g°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
