Does water boil faster with or without vinegar?
Pure water boil faster.
Vinegar evaporates quicker then water because the acid inside of vinegar causes the sun to make the molecules inside the vinegar to boil faster then the water so then the molecules inside the vinegar will break apart faster until the vinegar is completely gone Acetic acid enthalpy of vaporization is lower compared to the same property of water.
Water with salt will actually take longer than water without salt to evaporate. This is due to boiling point elevation. If you put a solute into water, it will make it more difficult to boil, and therefore will boil at a higher temperature. Since it takes longer for the salt water to boil, it will take longer for it to evaporate as well
Does salt added to water make the water heat up faster than water without salt added and if both are heated to a boil?
NO Normal water boils faster because salt (sodium chloride) breaks up very slowly and since its salt water. The salt binds itself with the molecules of the water therefore increasing the boiling point, hence making it slower to boil. In comparison to normal water, salt water takes longer to boil than normal water.
