What is surface tension give its SI unit?

What is surface tension give its SI unit?

Surface tension, represented by the symbol γ (alternatively σ or T), is measured in force per unit length. Its SI unit is newton per meter but the cgs unit of dyne per centimeter is also used.

Which of the following is unit and dimensional formula for surface tension of a liquid?

Or, T = [M1 L1 T-2] × [L-1] = M1 T-2. Therefore, surface tension is dimensionally represented as M1 T-2.

Does tension and surface tension dimensional formula?

a) Tension and surface tension. Since tension is a type of force, it will also have the same dimensional formula as the dimensional formula of force i.e. [MLT-2].

How is surface tension related to surface?

Due to the surface tension of the soap solution, a force ‘F’ will act on each arm of the frame. Hence, surface tension = surface energy per unit area. Thus, surface tension is equal to the mechanical work done per unit surface area of the liquid, which is also called surface energy.

How do you calculate surface tension from surface energy?

Work done by the excess pressure is stored in the form of potential energy. = surface tension × increase in surface area.

What are the dimensions of tension?

Or, Tension = [M1 L0 T0] × [M0 L1 T-2] = M1 L1 T-2. Therefore, the tension is dimensionally represented as M1 L1 T-2.

What is surface tension and surface energy derive the relation between surface tension and surface energy?

So, surface tension of a liquid is equal to the work done in increasing the surface area of its free surface by one unit. In other words, surface tension is equal to surface energy per unit area. Es​=TΔA. The unit of T is Jm−2 and its dimensional formula is [M1L0T−2]

What are the dimensions of surface tension?

The units for surface tension are therefore newtons per metre (Nm-1) and the dimensions are ML0T-2. The following table gives the surface tensions of some common liquids. The surface tension of a liquid decreases with increase in temperature and vanishes at the critical temperature.

What is the symbol for surface tension?

Surface tension, represented by the symbol γ (alternatively σ or T), is measured in force per unit length. Its SI unit is newton per meter but the cgs unit of dyne per centimeter is also used.

What is surface tension in fluid mechanics?

Surface tension in fluid mechanics is the Elastic like force that exists on the surface of the body, especially that of a liquid which tends to minimize the area of the surface, caused by asymatries in the intermolecular forces between surface molecules.

What is the definition of high surface tension?

Surface tension. Because of the relatively high attraction of water molecules for each other through a web of hydrogen bonds, water has a higher surface tension (72.8 millinewtons per meter at 20 °C) compared to that of most other liquids. Surface tension is an important factor in the phenomenon of capillarity .
