Surface Tension – Examples, PDF


When you look at the buoy floating on the ocean as a visible marker, it floats on the surface of the ocean. This occurs because of the relationship between the water’s surface tension and the density of the buoy.

What Is Surface Tension

Surface tension is a quality exhibited by liquids, primarily water, that would resist and bounce force back. Not only that but this is also the ability of liquids to cause buoyancy on objects and have an elastic surface. This allows boats to float on water and emulsion to occur in water.

How To Calculate Surface Tension

The surface tension of water can be solved through the formula of T = F/L. Where T is the surface tension (N/m), F is the amount of force exerted per unit of length (N or newtons), and L is the overall length of the force covered (m or Meters).

Step 1: Write Down the Formula

Begin by writing down the formula of surface tension on a notebook or digital note-taking software. Just remember what each measurement of those variables means and what measurements they are supposed to be on.

Step 2: List the Given Numbers and Ensure The Correct Measurement

It is important to list out the given numbers as it will help you analyze and differentiate the variables from each other. Not only that but you must also ensure that the given numbers match the measurements asked by the formula, and convert as needed.

Step 3: Substitute the Numbers to the Formula

After you have listed the given numbers and ensured the correct measurement, you must correctly substitute the numbers to the correct variables. Doing this will result in a solvable equation.

Step 4: Find the Missing Value

When you have finished substituting the numbers in the formula and creating the equation, you must find the missing value in the equation. The missing value will always be on the left side of the equation, which means you must move the variables appropriately.

Step 5: Convert the Value to the Correct Measurement

You must ensure that the value you found has the appropriate measurement. If it isn’t the measurement that is being asked, you must convert it to the correct measurement.

FAQs

What causes surface tension in water?

Water molecules are very different when compared with most objects’ molecular structures. Because of the way water molecules hold onto each other and fill the spaces between the molecules, the surface tension of water is higher than most liquids. This allows water molecules to act more dense than most objects, making water act as an elastic surface. This is also the reason why aquatic animals in the oceanic ecosystem, oceanic food web, or oceanic food chain, can move about in the water.

What causes surface tension?

Most liquids are formed of cohesive molecules that conduct a specific amount of force with one another creating an elastic surface. This phenomenon mostly occurs on the surface of the liquid where there are the least amount of liquid molecules. The surface of the liquid with the least amount of liquid molecules has a greater force of attraction as compared to the lower parts of the liquid, which would create the elastic surface of the liquid, therefore, causing surface tension.

Is surface tension a chemical or a physical property?

Surface tension is a physical property as this phenomenon is caused by the physical structure of the water molecules. This fact alone makes it very clear that surface tension is a physical property rather than a chemical property. Not only that, but another proof can come in the form of heating water to its boiling point which causes a physical change in the water, not a chemical change. When water is brought to its boiling point it will then temporarily have a surface tension of 0, which will return to its normal value when water returns to its room temperature. This is then a sign that surface tension is a physical property because chemical properties are permanently changed when a chemical change occurs.

Surface tension refers to the ability of water to act as a buoyant and rubbery surface. This ability allows objects with a lower density of water to float to the surface of the water. Not only does surface tension allow things to float, but this property will also allow bubbles and other pockets of air to appear on the surface.
