A scientist studies the amount of food gerbils eat based on how much
exercise they get. He has 100 gerbils. The scientist has each gerbil perform a
different amount of exercise and records how much food the gerbil eats.
What is the responding variable in this experiment?
O
A. The total number of gerbils
O
B. The amount of exercise performed by the gerbil
O
C. The amount of food eaten by each gerbil
O
D. The amount of sleep each gerbil gets

the answer is 303.15 or 303

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
