Water molecules climbing upwards against the force of gravity. Surface tension of water is weakened by hydrogen. Choice C C Surface tension allows water to support small objects if they are placed carefully on its surface.

Why do you measure the internal diameter of the capillary tube in two mutually perpendicular directions. Surface tension is the property of water in which. Which of the following describes surface tension in water.

In the absence of gravity the drop would minimize the surface area in order to minimize tension which would result in a perfectly spherical shape. The surface tension of water is 7275 10 2 N-m 1 at 20 C. Which of the following describes surface tension in water.

Write the letter of your answer in the blank 6. Choice A The ice molecules have higher kinetic energy than the liquid water molecules causing them to float. It occurs when the temperature in.

Surface tension is expressed in units of force per unit length or of energy per unit area for instance Nm or Jm 2. Hence the dimensional formula of surface tension is MT-2. Is there any difference in surface tension values among tap water distilled water.

Surface tension allows water to support small objects if they are carefully on its surface d. Surface tension is caused by water molecules repolling one another c. Polar covalent bonds between molecules at the surface of the water provide adhesion which supports the weight of the insect.

Surface tension is caused by water molecules. Water tends to be see-through. Surface tension is the property of water in which.

Surface tension occurs due to ionic bonding. The shape of the drops is caused by the surface tension of the water. - 14362981 AvaMaria8452 AvaMaria8452 1 week ago Science Elementary School answered Which of the following describes surface tension in water.

Surface tension allows water to support small objects. The surface tension value depends on the number of impurities there are in the water. Solving further we get.

MLT -2 L -1. Surface tension is the force that holds atoms or molecules of the same substance together when they are in contact with another substance. The surface tension of a liquid results from an imbalance of intermolecular attractive forces the cohesive forces between molecules.

2 It has a high boiling point and has a high specific heat. Choose 1 Choose 1 Choice A A Surface tension occurs due to ionic bonding. The property of the surface of a liquid that allows it to resist an external force due to the cohesive nature of its molecules SourcesUsage.

1 See answer. Which of the following describes surface tension in water. It seems to defy the laws of physics but a paper clip made.

Water tends to push up into a dome over a container before it finally spills. Hydrogen bonds between molecules at the surface of the water provide surface tension which allows the water surface to. 8 m s s 2.
