Nijar did an experiment to test a hypothesis that baking soda is just as effective a cleaner as bleach. He found this not to be true because more bacteria grew on surfaces cleaned with baking soda. Was there any benefit to Nijar's failed experiment? A. Yes, all the lab equipment can be used again.
B. No, Najar did not discover which product is the better cleaner.
C. No, Nijar wasted his time testing this hypothesis.
D. Yes, Nijar's findings contributed to scientific knowledge.

the answer is false because not all countries have geysers under their crust. for example, iceland uses geothermal energy because it is available every in their country.  

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

lol for the pointsss
