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.
Surface tension of water on adding detergent to it?
Decrease
Why did tension between the superpower increase and decrease?

Why can a sewing needle can float on the surface water in a glass?
Yes if the surface tension of the water is not broken. If you are careful you can place a needle on the surface of the water in a glass. Also if you reduce the surface tension with detergent (just a very little is enough) the needle will sink because it's density is greater than that of the water. NO (if the surface tension of the water is broken, a needle cannot float on the surface of water. This is because the needle has higher density than water (density is mass divided by volume).
Is surface tension increases or decreases with increase in temperature?
it is because as temperature increases, the particles in the water surface move further apart thus reducing the surface tension
Why do you has to decrease surface tension for cleaning the cloths?
Wht do we has to decrease the surface tension for clean the clothes
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 the effect of pH on surface tension?
For most liquids, an increase in pH results in decreased surface tension. This has been attributed to lower attraction force between molecules when pH rises.
How do you break the surface tension?
Adding surfactants the surface tension decrease.
What is the relationship between density and surface tension?
as we know the relation between surface tension and temperature is inverse, and that of temperature and density also has inverse proportion, then it is clear that the '''surface tension is directly proportion to the density'''.
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.
Effect of Temperature on Surface Tension?
surface tension decreases with the increase of temperature
Surface tension of water on adding detergent to it?
Decrease
What is the effect of increase of temperature on surface tension?
Surface tension decreases as temperature increases.
Is there a way to increase the surface tension of water?
The surface tension of "pure" water against air at 20 degrees C is 72.75 dynes/cm. This increases with cooling and decreases with heating. Most inorganic solutes increase the surface tension of the solution when dissolved in water. Most mineral acids decrease the surface tension of the solution in water (sulfuric acid is the most obvious exception). Most organic compounds decrease the surface tension of the solution in water (organic acids and alcohols are often exceptions). It is important to note that we are talking about increasing and decreasing the surface tensions of solutions of these things in water with respect to distilled water. In order to change the surface tension of distilled water, just changing the temperature will suffice. PS : At 0 degrees Celsius, the surface tension of water is 75.6 dynes/cm, at 100 degrees it is only 58.9 dynes/cm.
If you change the length of the string will it make the frequency increase or decrease?
increase the length of the string means decrease the tension in the string, therefore as the tension decreases the frequency will drop due to loosen of the string.
