urgent please help Which factors add to the greenhouse effect and are caused by human activities? Select two options. a decrease in the amount of dust in the atmosphere a decrease in the amount of water on Earth’s surface an increase in gases in the atmosphere that absorb heat an increase in surfaces that radiate energy into the atmosphere an increase in the amount of solar radiation that reflects into space

I would say that the answers are an increase in gases in the atmosphere that absorb heat an increase in surfaces that radiate energy into the atmosphere, and a decrease in the amount of water on Earth’s surface

Explanation:

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
