how much water are we pumping out of the ground using wells in the us alone?

Reports have shown that the US alone uses 26% or 79.6 billion gallons of groundwater each day.

Groundwater can be described as the water which is accumulated in the cracks and other openings of the beds of rocks. Groundwater is considered to be a significant supply of water for a country. In the United States, groundwater is considered to be 20 to 30 times greater than the water present in lakes, rivers and streams.

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
