The surface tension properties of fluid substances remain largely stable, CSC but can be altered by changes in temperature, chemicals that alter molecular bonding properties, oxidation and the presence of impurities. Let us consider the effect of these four conditions on surface tension:
1. Temperature
As the temperature decreases, the surface tension increases. Conversely, as the surface tension decreases, the strength decreases. As the temperature increases, the molecule becomes zero at the boiling point and disappears at the critical temperature, thereby becoming more active.
2. Chemical additives
Chemicals and Surface Tension Adding chemicals to a liquid changes its surface tension properties. The effect of adding an unrelated chemical to a substance to change its surface tension is demonstrated by the example of putting soap (a surfactant) in water to lower the surface tension, which can make dirt on your hands easier Easy with water.
3. Oxidation
Oxidation directly affects surface tension. As the surface tension increases, the intermolecular forces increase. Oxygen in the atmosphere is known to lower the surface tension of various substances. Presence of Impurities The presence of impurities on or dissolved in a substance directly affects the surface tension of a liquid. For example, when highly soluble impurities are added to water, the surface tension of the water will increase.
4. Surfactant
Now that we have considered the effect of temperature changes, the addition of chemicals, oxidation, and the presence of impurities on surface tension, we should next consider how surfactants change over time and how we can observe and measure this effect.
