Well If you have a pie pan filled with milk and then drop 4 diffrent colors of food coloring droped in but not touching then get a tooth pick with detergent on it and touch it in the foodcoloring will swirl out like tie die in the pan.
Actually, detergent causes the surface tension of water to decrease. Surface tension of water is caused by an intermolecular force called hydrogen bonding. The detergent interferes with the hydrogen bonding occurring between H2O molecules so, therefore, detergent decreases surface tension.
The surface tension of water is 72 mN.m-1 in SI units. Adding detergent lowers the surface tension to less than this number. Some common ones will lower it to 25mN.m-1
This is how washing up liquid works. The surface tension of water is high and the surface tension of grease and oils and fats etc is lower. Adding a detergent bridges the energy gap
detergents break up the surface tension by perturbing hydrogen bonding on the surface: the detergent's apolar chain ends will prefer to stick out of the water (that is to say, the water will preferentially form hydrogen bonds with each other making the chain ends sticking out entropically favoured: if the apolar chains were in the bulk of the water it would force the water molecules to adopt and "ice-like" ordered state to maximize hydrogen bonding) so yeah, surface tension will be lowered with addition of detergent.
When detergent is added to water, the detergent molecules break down the cohesive attractive forces of the water molecules at the surface. Thus, the surface tension is broken.
Yes it does increase the surface tension THE detergent causes the surface tension of water to increase
It increases
decreases
Decrease
False. When detergent or soap is added to water then it surface tension decreases.
There is an effect on Surface Tension when detergent is put in the water. I am doing an experiment for my upcoming Science fair and i am doing a Detergent Powered Boat/Surface Tension...I have tested it many times with and without detergent, when it doesn't have detergent it floats and then sinks after 5 seconds but with detergent it zips through the water...I can not give you the reason for this as i am myself still researching on why this is!
since milk has water as a main component, water has surface tension as the forces adhesion( sticks to stuff like the side of the glass) are stronger that the cohesion (makes water keep to itself) forces
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.

If you have floated a needle on the surface of the water in a glass then adding a little detergent will cause the needle to sink. This is because the presence of the detergent changes the surface tension of the water so that it can no longer support the needle.
It weakens the surface tension of water allowing us to blow BUBBLES!! :D
The surface tension of water can be broken by adding dishwashing detergent to the water. This can be demonstrated by filling a bowl with water, then floating a needle in it. This may sound almost impossible, but it can be easily achieved by placing the needle on a tissue, then carefully floating it on the water. When the tissue sinks, the needle should remain on the surface. It is prevented from sinking by the water's surface tension. Carefully add one drop of dishwashing detergent, and the needle will sink. You can prove this was due to the surface tension being broken by trying to float the needle again. If you added enough detergent this should be impossible, as detergent acts as a wetting agent and breaks the surface tension.

Some mood music.

Because the detergent reduces the surface tension of the water.
It will increase the surface tension of water hence temperature decreases. If you add phenol to water temperature increase as it decreases the surface tension.
