Which of the following illustrates a phase change? a. gasoline evaporating into the air b. a helium balloon rising into the sky c. air leaking from a tire d. plasma erupting from the sun

A. Gasoline evaporating into the air

Explanation:

The matter can exists in any of the three forms that are solid, liquid and gas. Phase change may occur in different forms such as solid, liquid and gas. The gasoline is a volatile liquid which when exposed to the air can change it's phase from liquid to vapors on evaporation.  

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
