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.
Why the change in surface tension is much less when sodium chloride is added to water in place of an equivalent amount of ethanol?
Sodium chloride increase the surface tension of water and methanol decrease the surface tension of water.
What is surface tension coefficient?
define coefficient of surface tension
Why kerosene float on water?
Kerosene is less dense than water.
What is surface tension in hydrocarbons?
Each liquid hydrocarbon has a different surface tension.
Why kerosene has more surface tension than water?
It doesn't.

What do you expect to see if the liquid surface tension is less than or equal to the critical surface tension of a surface?
the lack of a surface.

Sodium chloride increase the surface tension of water and methanol decrease the surface tension of water.
Is kerosene oil use full to kill the mosquito larva?
approximately 1 ounce of kerosene for every 15 sq ft of water.
What is a force that acts on particles at a liquids surface?
Surface tension. It always tends to acquire minimum surface area thats why water droplets form spherical shape.
Why does water have higher surface tension than oil?
Because of the polarity of the water molecule, hydrogen bonds form between them. This results in the higher surface tension. Oil is nonpolar, so hydrogen bonds do not form between the molecules, so the surface tension is less.
Surface Tension is found in what?
Surface tension is found in Liquid
What is surface tension coefficient?
define coefficient of surface tension
What liquid have the strongest surface tension?
Mercury is the liquid with the strongest surface tension.
Is the inward force among the molecules of a liquid?
The inward force among the molecules of a liquid is Surface Tension
What is the effect of sodium chloride on the surface tension of water?
The surface tension of water is increased for salted water.Sodium chloride increase the surface tension of water.
