When sufficient quantity of heat has been added to reach the boiling point of a solution, what happens to any additional heat added? a) additional heat is used to maintain the boiling of the liquid as the process is endothermic and requires continued input of energy. b) additional heat raises the temperature of the liquid which in turn increases the rate at which boiling occurs. c) additional heat lowers the intermolecular forces of the liquid which in turn increases the volatility of the liquid. d) additional heat alters the viscosity and the surface tension of the liquid which raises the vapor pressure and increases the boiling point which is why you must continually heat the solution. e) none of the above are correct statements.
Since the sample is an unknown solid, I will have to make a solution without knowing exactly what to mix. In your expertise, how much of the solid do you expect to dissolve in what volume of water and what is your reasons for choosing these amount..
