Why do we see different phases of the moon.

The Moon itself does not generate light; it is lit up by the Sun. As the Moon orbits the Earth, the portion of illuminated Moon that we see changes – giving rise to the phases of the Moon. ... Sometimes the Earth, Moon and Sun are aligned such that the Earth is directly between the Sun and the Moon.

Shadows

Explanation:

The Moon Dosent Produce Light,Therefore In Diffrent Cycles Shadows Cover Diffrent Parts Of The Moon Dpending Where The Suns Light Is Hitting It.

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
