when raymond observes certain natural phenomena, he often forms ideas about their causes and effects. suppose that raymond
surmises that leaves change color in autumn due to scarcity of sunlight. in order to test whether his idea is accurate, he must first
construct a falsifiable
that defines a clear relationship between two variables. raymond's next step is to
that would isolate and test the relationship between the two variables. this task can be pretty
daunting because raymond will need to identify and eliminate any
variables that could confuse test results

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
