The 10 properties of liquid

The 10 properties of liquid and example pictures

1. Properties of liquids Surface tension Capillary action Viscosity Incompressibility Diffusibility evaporation Cooling effect of evaporation Vapor pressure Boiling point Heat of vaporization

2. Surface tension Is the force that causes the molecules on the surface of a liquid to “tighten their hold to one another”, creating the effect of a thin membrane on the surface .

3. Cohesion Cohesion refers to the attraction of molecules to other molecules of the same kind.

4. Cohesion creates Surface Tension

5. Adhesion

6. Adhesion  is the attraction of one kind of molecule to a different kind, and it can be quite strong for water, especially with other molecules bearing positive or negative charges.

7. Capillary action describes the spontaneous flow of a liquid into a narrow tube or porous material. This movement does not require the force of gravity to occur

8. Adhesion enables water to “climb” upwards through thin glass tubes (called capillary tubes) placed in a beaker of water. This upward motion against gravity, known as  capillary action , depends on the attraction between water molecules and the glass walls of the tube (adhesion), as well as on interactions between water molecules (cohesion).

9. Viscosity

10. Viscosity is a measure of how much a liquid resists flowing freely.

11. Incompressibility of liquid Liquid molecules are already close touching one another so when force is applied, it can be compress a little. Compared to gas there is a great compression.

12. Diffusibility A property of liquid that makes another liquid or a solid may dissolve or diffuse through it.

13. Evaporation

14. Evaporation is the process by which an element or compound transitions from its  liquid state  to its  gaseous state below the  temperature  at which it boils; in particular, the process by which liquid water enters the atmosphere as water vapor.

15. Cooling effect of evaporation Evaporative cooling uses the fact that water will absorb a relatively large amount of heat in order to evaporate.

16. Vapor pressure In a close container, the space above the liquid becomes saturated with vapor and an equilibrium state exists between the liquid and vapor.

17. Boiling point Is a temperature at which the vapor pressure of a liquid is equal to the external pressure.

18. Heat of vaporization Energy required to change a liquid at its boiling point.
