Want this question answered?
As heat increases the surface tension decreases.
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.
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 decreases the surface tension of the water.
Surface tension. It always tends to acquire minimum surface area thats why water droplets form spherical shape.
False. When detergent or soap is added to water then it surface tension decreases.
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.
surface tension decreases with the increase of temperature
As the temperature rises, 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!
it decreases it.
Surface tension decreases as temperature increases.
As heat increases the surface tension decreases.
Decrease
it decreases it.
It weakens the surface tension of water allowing us to blow BUBBLES!! :D
