because they form London Dispersion bond which is the weakest among the inner-molecular bonds
Surface tension typically decreases as the pH of a solution becomes more acidic or basic. This is due to changes in the concentration of ions at the liquid-air interface, which affects the attractive forces between molecules. In general, a change in pH can disrupt the hydrogen bonding between water molecules, leading to a decrease in surface tension.
Soap will lower the surface tension of water. Like any surfactant soap will lower the surface energy by disrupting the strong inter-molecular hydrogen bonding that confers such a strong surface tension to water.
Reduction of surface tension in liquids can lead to changes in their behavior, such as increased spreading and wetting on surfaces. This is because lower surface tension allows the liquid molecules to spread out more easily, resulting in improved interactions with other substances.
Soapy water does have some surface tension to it but it is very negligible. However pure water have good surface tension due to strong hydrogen bonding. This is the reason a water strider bug can walk and paperclip will float on water.
Salt water has a lower surface tension compared to fresh water. This is because the presence of salt ions disrupts the hydrogen bonding between water molecules, reducing the cohesive forces at the surface of the water.
Surfactants, which are molecules that lower surface tension, can be found in serous fluid. These molecules help prevent alveoli in the lungs from collapsing by reducing the surface tension of the fluid lining the alveoli.
Kerosene has less surface tension than water because its molecules are less polar and can't form hydrogen bonds as easily as water molecules. This results in weaker intermolecular forces between kerosene molecules at the surface, leading to lower surface tension.
Acetone has a lower surface tension than water because it has weaker intermolecular forces due to its molecular structure. The molecules in acetone are less able to attract each other compared to water molecules, resulting in a lower surface tension.
Surface tension is lower at higher temperatures.
Surface tension of water decreases as temperature increases. At lower temperatures, water molecules are more closely packed, leading to stronger intermolecular forces and higher surface tension. As temperature rises, water molecules gain kinetic energy and move more freely, causing weaker intermolecuar attractions and lower surface tension.
Detergent has the effect of reducing the size of the water molecules thereby reducing the surface tension of the water. This allows for the small water molecules to integrate themselves farther into fabric to remove contaminants.
Lowering surface tension in a liquid system can be achieved by adding surfactants or reducing the temperature of the liquid. Surfactants are substances that can reduce the attraction between molecules at the surface of the liquid, making it easier for the liquid to spread out. Lowering the temperature can also reduce surface tension by slowing down the movement of molecules at the surface.

The surface tension of a glycerol solution can vary depending on the concentration of glycerol and temperature. In general, the surface tension of a glycerol solution is lower than that of pure water due to the glycerol molecules disrupting the hydrogen bonding between water molecules at the surface.
yes it is lower than the surface tension of water
BEcause as the name suggest,first of all it is a tension or like a pull.Molecules of water are freely movable comparatively to solid. So at the surface there is jiggling of molecules ,some goig to atmosphere and some are being pulled back by lower molecules who want to come at surface.
