Mineral spirits is a mixture of molecules similar to the ethane, diagrammed above, but larger in size. A. Isopropyl alcohol will have a higher boiling point than water because the forces between the molecules are greater. Surface tension is the energy required to increase the surface area of a liquid by a unit amount and varies greatly from liquid to liquid based on the nature of the intermolecular forces, e.g., water with hydrogen bonds has a surface tension of 7.29 x 10 -2 J/m 2 (at 20C), while mercury with metallic bonds has as surface tension that is 15 times Does water or rubbing alcohol have a higher density? However, if you add alcohol, instead of water interacting only with other water molecules, it now interacts (less strongly) with alcohol, and the surface tension of the mixture will be lower. Alcohol and Water Alcohol has one OH bond which is polar but a large portion of the molecule is made up of CH bonds which are nonpolar. In contrast, oils have few, if any, hydrogen bonds amongst their large, organic molecules. These cookies ensure basic functionalities and security features of the website, anonymously.
