(A) Newton/meter
(B) Newton/meter2
(C) Newton
(D) Kilogram meter/second
Newton/meter is the SI unit of surface tension. Surface tension is measured in Newton/meter (N/m), a SI unit. Surface tension is the propensity for fluid surfaces to constrict to their smallest practicable surface area. Agnes Pockels made the discovery that contaminants affect surface tension.

Explain Surface Tension
At room temperature, water has one of the greatest surface tensions of any liquid at roughly 72 mN/m. Mercury, liquid metal with a surface tension of over 500 mN/m, is the only liquid with higher surface tension.
Water’s surface tension is extremely high. This characteristic, which is essential to living on the surface of aquatic habitats, enables capillary action in plants. Intermolecular forces at the contact have an impact on surface tension. Surface tension is influenced by the type of liquid, the surroundings, and the temperature. Surface tension will be high in liquids with strong, attractive intermolecular forces between molecules.
Summary:
What is the SI unit of Surface Tension? (A) Newton/meter (B) Newton/meter2 (C) Newton (D) Kilogram meter/second
Newton/meter is the SI unit of surface tension. The tendency for fluid surfaces to contract to the smallest practical surface area is known as surface tension. Surface tension is affected by pollutants, as discovered by Agnes Pockels.
