Effect of Temperature and Salinity on Surface Tension of Water

WebAs temperature increases, molecules of liquid become more active and they move more rapidly; therefore, the intermolecular forces are more instable. Surface tension decreases … WebApr 25, 2024 · As the temperature of the water is increased the surface tension of the water decreases. When the temperature is increased, the average separation between the molecules increases, and due to that, the cohesive forces decrease. WebAug 14, 2024 · At a pressure greater than 1 atm, water boils at a temperature greater than 100°C because the increased pressure forces vapor molecules above the surface to condense. Hence the molecules must have greater kinetic energy to escape from the surface. Conversely, at pressures less than 1 atm, water boils below 100°C. black button up shirt women\u0027s
