In an experiment to measure surface tension of completely wetting liquid, the capillary was dipped in liquid. The level of water in beaker was measured using travelling microscope to be 1.43cm. The level of water in capillary was measured to be 6.23cm. The readings for inner diameter were 0.00cm and 0.32cm respectively. Neglect the expansion of capillary and water on heating. (A)% error in measurement of h is 0.4% (B) % error in measurement of surface tension is 6.46% (C) if temperature increases, level of water in capillary will be less than 6.23cm. (D) s=0.38±0.04 N/m

Define surface tension and explain how it is responsible for the phenomenon of capillarity. A glass tube with an inner radius of 0.5 mm is dipped into water. The water level inside the tube is observed to rise to a height of 20 mm above the external water level. Calculate the surface tension of water.

An R mm radius glass tube is inserted into the water at 20°C in a cup. At 200 C the surface tension is 0.0728 N/m. The angle of contact is Theta degree.Here,R=0.6 mmTheta=(180/3)degreeDetermine the capillary rise of water in the tube in millimeters unit.

The capillary of a dropper has an internal radius of 0.5 mm. It is filled with liquid X and then allowed to flow into a capsule.After collecting 200 drops of liquid in the capsule, they are weighed, and the mass of liquid collected is found to be 𝑚 =10 g.1. Determine the value of the surface tension constant of this liquid. Assume the wetting angle of this liquid to be 30∘.2. Liquid X is a medication; a patient needs to take 0.1 g every 12 hours. How should the patient administer themedication?

When the temperature increases, the surface tension of water

The surface tension of soapy water is 0.0250 N/m. What is the height of the water in a capillary tube of diameter 2.00 mm?
