The manufacture of 1000 ft2 of 5/8 in. thick gypsum board contributes 277 kg CO2eq. If a typical gypsum board is 4 ft x 8 ft x 5/8 in. thick, how many tons (U. S.) of CO2eq are produced for the manufacture of 50 of those typical sized boards

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

so she was walking and she stepped on warm jeffy , uh uh uhh dadye i just pooped my pants
