What must happen to surface tension in order to clean a surface?
Surface tension must be reduced in order to clean a surface effectively. This can be achieved by using a cleaning agent or detergent that helps to break the surface tension, allowing the cleaning solution to spread and penetrate the surface for thorough cleaning.
What is the correct order of the steps for cleaning in sanitizing?
The correct order for cleaning and sanitizing is: 1) remove debris and dirt from the surface, 2) wash the surface with soap and water, 3) rinse the surface with clean water, and 4) apply a sanitizing solution to kill germs and bacteria.
What is the best way to clean a stainless steel chain?
To clean a stainless steel chain, start by wiping it down with a clean cloth to remove any surface dirt. Then, mix warm water with a gentle dish soap and use a soft-bristled brush to scrub the chain. Rinse thoroughly with clean water and dry with a soft cloth to prevent water spots.
What is parachore and its effect in chemistry?
Parachor is a quantity relating the surface tension to the molecular weight and density. It is defined by the formula (surface tension ^1/4) * M / d. Parachor is used in solving structural problems. Sugden defined in 1924 parachor as (surface tension in mN/m)^(1/4).(molar volume in cm^3/mol). This definition is used up to now and it results in usual parachor values of the order of magnitude of 100. Therefore, parachor is a derived quantity like any other and its unit is (mN/m)^(1/4).cm^3/mol. This unit is so bizare in the light of usual experience that most authors do not dare give it in their texts and prefer not to give any unit. Owing to this fact, there has arisen the mistaken impression that the parachor has no unit. S. Sugden, J. Chem. Soc. Trans. 125 (1924) 1167--1177, from contemporary literature see M. Souckova et al. J. Chem. Thermodynamics 83 (2015) 52-60
Is laundry liquid an acid or a base?
Soaps, including laundry detergents, are slightly alkaline ("basic"). Most organic stains (foods, sweat, blood) are slightly acidic, so being slightly alkaline helps detergent dissolve these substances. But the real reason that detergents help clean things is because of the way they interact with water. Water has surface tension, and tends to bead up on surfaces. Detergents break surface tension, and make water spread out over surfaces (like you dirty jeans) more evenly, helping to loosen soil there. In addition, soap molecules have one end which likes to "stick" to water, and the other end which likes to "stick" to oily substances (like grime and other dirty stuff), so they help to loosen dirt from surfaces and mix it with the water better.

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.
How are small insects able to walk on the surface of water?
The oil on their feet is strong enough to repel the water and there weight is spread out enough that when their feet touch the water, the oil and the water repel each other like when you pour oil on water the oil floats on the top... same principle
What is water's surface tension?
Here are some explanations of surface tension:Surface tension is a property of the surface of a liquid that causes it to behave as an elastic sheet. It allows insects, such as the water strider (pond skater, UK), to walk on water too. It allows small objects, even metal ones such as needles, razor blades, or foil fragments, to float on the surface of water, and it is the cause of capillary action.5.18 pounds / feet at 0 degree Celsius. Or as I remember it is 72 dyne / centimeter at 25 degree Celsius. The surface tension of water is the force required in order to float at the water's surface, hence making water to behave like an elastic sheet.Water surface tension is contractive tendency of the surface of a liquid that allows it to resist an external force. The beading of water on a waxy surface, such as a leaf, is an example of water surface tension.

What is the reason that a crushed tin ball of foil will sink and and flat piece of it floats?
A flat piece of tin foil may float on top of water due to surface tension. A crushed ball of foil does not have near the amount of surface area in contact with the surface of the water, so the surface tension is not sufficient to keep it suspended. Note that if you place a flat sheet of foil in the bottom of a container and pour water in on top of it however, it will not rise to the top to float; you have to place it on top carefully in order to get it to float.
What would happen first in order for a new island to be created by volcanic eruption?
Magma must find its way toward the surface of the crust.
A block is connected to the surface of a table via a string and an electric field is switched on perpendicular to it what will be the tension in the string when it becomes parallel to the field?
In order to know how much tension is on an object, you need to know how much force is being exerted by the object. The formula needed to find out how much force is on an object is T1F1.
What factor would you have to multiply the tension in a taut spring in order to double the wave speed?
You would need to multiply the tension in the spring by four in order to double the wave speed. This is because the wave speed is proportional to the square root of tension in a taut spring.
If you gave your Yorkshire Terrier a bone what can happen?
Some dry food or bone should be given to Yorkshire Terrier to chew, in order to keep its teeth strong and clean.
What must particles in a liquid overcome in order to break away from the surface and evaporate?
Particles in a liquid must overcome the intermolecular forces holding them together, such as hydrogen bonds or van der Waals forces, to break away from the surface and evaporate. This requires sufficient energy to disrupt these forces and transition from the liquid phase to the gas phase.
