... a) Water evaporates faster at 40oC than at 20oC. More hydrogen bonds are breaking due to higher T. b) Propane (C3H8) boils at a lower temperature than water. Propane held together by weaker dispersion forces (NP). c) Oil is not soluble in water. Propane is nonpolar & is not attracted to polarity of ...
