Which is a characteristic of surface tension? a. The molecules of a liquid form a porous network at the liquid’s surface. b. The molecules of a liquid attract each other enough to prevent penetration by other molecules. c. Surface tension is the same in various types of liquids. d. Surface tension is greater in a nonpolar covalent liquid than a polar covalent liquid. Between which species will ionic bonds be present? a. two ethanol molecules b. two chloride ions c....

9. As a simple model of surface tension, the surface of a polar liquid, like water, can be viewed as a series of dipoles strung together in a stable arrangement in which the dipole moment vectors are parallel to the surface and all point in the same direction. Suppose that something presses inward on the surface, distorting the dipoles as shown below (a) Show, qualitatively, that the two slanted dipoles exert a net upward force on the dipole between them,...

What is the strongest type of intermolecular force that must be overcome to convert liquid water to water vapor? O lon-dipole forces Hydrogen bonds o Covalent bonds O Dipole-dipole forces O London dispersion forces

The boundary between liquids, like water, and gases, like air, is an ordered arrangement of hydrogen bonding of water molecules to each other at the surface and below the surface, but not with the molecules of gas in the air above the surface. This phenomenon is known as surface tension and is largely due to which property of water? cohesion adhesion heat of vaporization evaporative cooling

3. Surface tension of a water strider For an animal the size of a human, surface tension seems to be a rather small and insignificant force (though it plays an important if unnoticed role in our breathing). But as animals get smaller, surface tension gets increasingly significant. (The weight of the animal goes down with the cube of the size while the surface tension only decreases linearly.) For animals like the basilisk lizard and the jacana (bird), they appear to...
