which phenomenon occurres when soap comes in contact of water
Answers
Answer:
The effect of detergent on surface tension brings a non-adhesive nature in water molecules. It does not stick to the surface of the glass. It happens because of the cohesive force in the water-detergent molecule. The exact thing appears when it comes to washing clothes with water.

Answer:
A superficial relationship: Soap on water
Explanation:
A bowl of water sprinkled with pepper flakes sits ready on Mahesh Bandi's kitchen countertop. Bandi, a professor of physics at the Okinawa Institute of Science and Technology Graduate University (OIST), wets the tip of a chopstick with liquid soap, amusement written on his face, and asks his dinner guests their predictions: what will the flakes do when the soap meets the water's surface?
He touches the chopstick to the water -- suddenly, the flakes flee from the center of the bowl. This is but a very simple example of the Marangoni effect, which Bandi studies inside his lab at OIST's Collective Interactions Unit.
Reported as early as 1686, the phenomenon results from a difference in surface tension -- the quality that causes a liquid surface to behave as though it were a stretched elastic membrane. The substance with higher surface tension pulls more strongly than the one with lower surface tension, pulling the flow of liquid toward it.
James Thomson, the elder brother of physicist Lord Kelvin, described the phenomenon in 1855 as "the curious motions commonly observed in the film of wine adhering to the inside of a wine glass." The very same force allows water striders to glide along the surface of a pond, and, as Bandi demonstrates, causes flakes to move across water. Yet, despite its ubiquity, the Marangoni effect is elusive.
"You can see it in your kitchen, but it is notoriously difficult to quantify," said Bandi. In a new study published in the journal Physical Review Letters, he and his colleagues present a method for doing just this by studying the phenomenon through three different independent measurements.
Liquid soap does several things when it touches a bowl of water: some of it spreads over the water's surface, while some begins dissolving in the water. The researchers found that these factors -- which together constitute the Marangoni effect -- can occur to varying degrees.
