Do all liquids have the same surface tension?

No, liquids have different surface tensions. Partly due to the strength of the force that bids the molecules together. Many liquids have what is called hydrogen bonding and water has a high value for hydrogen bonding. read more

No, liquids have different surface tensions. Partly due to the strength of the force that bids the molecules together. Many liquids have what is called hydrogen bonding and water has a high value for hydrogen bonding. VanDerWahls forces are anothe force that determins surface tension, the stronger the more the surface tension. read more

MERCURY has a higher surface tension than water. This highest surface tension between liquids is 487 mN/m at 15 0 C. read more

The nature of all liquids is that they do have surface tension. Surface tension is what holds liquids together, and stops them being gases. Water has particularly strong surface tension, which is why a molecule that is lighter than oxygen, let alone carbon dioxide, can be a liquid at room temperature, while both carbon dioxide and oxygen are gasses at room temperature. read more
