Does juice box have a surface tension?
No. Surface tension is a characteristic of liquids, not solids like a juice box.
What is the measurement describing the number of unit squares that cover a surface?
That's the area of the surface.
What is a measurement describing the unit squares that cover a surface?

What has to have more density for an object to float on water the object or water?
Normally the water - to float and object has to displace a volume of water equal to its mass. If its density is greater than that of water, the maximum mass of water it can displace is its own volume which, as the water is less dense that it, will have less mass than the object and it will sink. However, for small light objects the surface tension of water comes into play - it is possible to float a steel sewing needle (with a density greater than water) on water by gently dropping a clean needle on its side onto the water surface so that it does not break the surface tension. With a needle floating, adding a few drops of washing up liquid to the surface reduces the surface tension and the needle will then sink.
How could it be possible that an object with a density greater than that of water could float in water?
There are two ways to make an object with a density greater than water float on it: 1) reduce its density, for example by hollowing it out or adding further structures with a density [much] less than that of water so that it can displace a volume of water equal to its own weight and still have some of its structure above the surface of the water; or 2) Use the surface tension of water so that the object floats - dropping a steel sewing needle on its side very gently onto water will prevent it breaking the surface tension of the water and it will float, until such time as the surface tension is broken, eg by adding a few drops of washing up liquid or agitating the surface, when the needle will sink. (The needle needs to be clean.)
What is the Cgs unit of surface tension?
The CGS unit of surface tension is dyn/cm (dyne per centimeter).
What are compounds that lower the surface tension of water?
Unit cells
The unit of surface tension is?
Surface tension is basically a force acting on the surface of a fluid.so the units will be newtons(N) and dimensions are MLT-2But generally we talk in terms of surface tension coefficients which is surface tension per unit length.Vishesh MadanSurface tension is perpendicular force acting per uint length of an imaginary line stretched on the surface of a liquid. Therefore, SI units will be N/m, since the value of surface tension for all liquids is very low therefore it is commonly mentioned as mN/m. Dimensions formula for surface tension will be MT-2.In another case Surface tension is also measured as work done to streach a unit surface area of a film, in that case units will be J/m2.K Singh
Is surface tension scalar or vector?
Surface tension is a scalar quantity, as it only has magnitude and no direction. It represents the force per unit length acting parallel to the surface of a liquid.
What is surface tension.?
Surface tension is defined as the elasticlike force that exists at the surface.
How can you explain surface tension?
Surface tension is a property of liquids that arises from the cohesive forces between the molecules at the surface. It is responsible for the "skin-like" effect that allows some insects to walk on water. Surface tension minimizes the surface area of liquids to maintain their integrity and is measured in units of force per unit length.
Is surface tension is extensive property?
No, surface tension is an intensive property because it does not depend on the amount of the substance present. It is a property that is related to the structure and composition of the surface of the liquid.
What is the fromula of surface tension?
The surface tension doesn't have any formula,it's just a property on surface of liquid to hold out an external force. However it's dimensional formula is [MT-2], with its standard unit as Nm-1 .
Why the dimension of surface tension is MLT-2?
The dimension of surface tension is MLT-2 because it is defined as the force acting perpendicular to a unit length of interface between two fluids. The force per unit length has units of force/length, which can be expressed as MLT-2.
Why surface tension is scallar?
Surface tension is a scalar quantity because it represents the force per unit length acting perpendicular to a line drawn on the surface of a liquid. It only has magnitude and no direction.
What is surface tension and how does it work?
Surface tension is a property of liquids that arises from the cohesion between the liquid molecules at the surface. It is the force that causes the surface of a liquid to behave like a thin elastic sheet. Surface tension works to minimize the surface area of a liquid, resulting in phenomena such as the formation of droplets or the ability of certain lightweight objects to float on the surface of water.
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.
