Rubbing alcohol evaporates from your arm quickly, leaving a cooling effect on your skin. how do the molecules of gas compare to the molecules as a liquid? a. the gas particles move faster, have the same molecular composition, and have weaker attractions between them than the liquid particles. b. the gas particles move faster than the liquid particles, and the bonds of the molecules are broken during evaporation to allow gas atoms to spread apart. c. the gas particles move slower but have the same molecular structure and the same attraction between them as the liquid particles. d. the gas and liquid particles move at the same speed, but the bonds of the molecules are broken during evaporation to allow the gas atoms to spread apart.

The answer is option A "The gas particles move faster, have the same molecular composition, and have weaker attractions between them than the liquid particles." Some differences between a gas and a liquid is their physical characteristics, and also gas molecules move faster then liquids. Just like how liquid molecules move faster then solid molecules.

Hope this helps.  

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.  

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
