Why we use kerosene in ultrasonic diffraction but not water?
Kerosene has a lower surface tension and viscosity compared to water, which allows for better dispersal and diffusion of the ultrasonic waves. This helps create smaller and more consistent droplets for diffusion. Water has higher surface tension and viscosity, which can inhibit the dispersal and diffusion of the ultrasonic waves.
How does soap effects the surface tension if water?
the surface tension has bonds, and the soap breaks those bonds, so if the soap water is put onto a surface.. it will slip off
Does kerosene evaporate faster than water. why?
Yes, kerosene evaporates faster than water because it has a lower boiling point. This means that at normal temperatures, kerosene molecules have more energy to break away from the liquid surface and enter the gas phase compared to water molecules.
Which has more surface tension clean water or soapy water?
Yes, pure water is a one molecule based structure, which hold together better than a mixture. When soap or other chemical is added, it breaks surface tension by getting in the way of each water molecule. Try putting water drops on a penny to build a bubble, then add a small drop of soap to it, you'll see that when soap is added, the water bubble collapses.
Why does soapy water do not have surface tension?
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.
Which will evaporate first-water or kerosen?
Kerosene will evaporate before water, given equal volumes and similar environmental conditions. The reason: water has considerable surface tension, brought about by hydrogen bonding between its very polar molecules. Kerosene is a hydrocarbon, and is non-polar, which means its molecules do not have a positive or a negative end. Water's surface tension resists evaporation. Kerosene's lack of surface tension (because of its non-polarity) makes it evaporate more quickly.

This helps create smaller and more consistent droplets for diffusion. Water has higher surface tension and viscosity, which can inhibit the dispersal and diffusion of the ultrasonic waves.
Which spreads faster on the floor water or kerosene?
Water spreads faster on the floor compared to kerosene. This is because water has lower surface tension and higher adhesion properties, allowing it to cover a larger area quickly. Kerosene, on the other hand, has higher viscosity and lower adhesion properties, causing it to spread more slowly.
Does surface tension change when bleach is added to it?
Yes, surface tension can change when bleach is added to water. Bleach is a surfactant that can reduce the surface tension of water by disrupting the hydrogen bonding between water molecules. This can lead to a decrease in surface tension and cause water to spread more easily.
Does water temperature affect surface tension on a penny?
Yes, water temperature can affect surface tension on a penny. As water temperature increases, surface tension generally decreases. This means that with higher water temperature, the water is less likely to bead up and more likely to spread out on the penny, reducing the surface tension.
Surface tension of water at different 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.
Is there anything such as water tension?
Yes. It is more specifically called water surface tension and it is the result of water's ability to form hydrogen bonds.
How does soap effects the surface tension if water?
the surface tension has bonds, and the soap breaks those bonds, so if the soap water is put onto a surface.. it will slip off
Do you think Salt water will have more or less surface tension than plain tap water?
more

Does vegetable oil have more surface tension than water?
No. Vegetable oil's surface tension is approximately 34 dynes/cm while ultrafiltrated water is 72.40 dynes/cm.
