Why do you think we use asphalt and tars/waxes (heavier, thicker, higher boiling point fraction) in our roads and roof coatings? Why not use gasoline of diesel in a roof coating or road (what would it do, what is its problem)? b) Could you burn tar as a fuel in your car? If so, what would you have to do to it to make it work?

So3 that’s what i think

You would be correct, boiling water does disinfect contamination.    the property of disinfecting means to kill  germs, bacteria and other pathogens or contamination  that might cause an infection or cause a person to become sickly. a couple methods of disinfecting are using soap, other cleaning supplies or by simply "boiling" the contaminate.  the reason why boiling water disinfects certain attributes is because some cells cannot survive the heat and pressure.
