why does liquid behaves like a stretched rubber membrane? 1 Answer. The liquid molecules on the surface experience a downward force. So, they have greater potential energy. In order to have minimum energy, the free surface tends to contract to minimum area and hence behaves like an elastic stretched membrane.
What is stretched membrane in surface tension? The answer is surface tension, the way that a liquid surface acts a little like a stretched elastic membrane. Surface tension is caused by the forces of attraction between the particles of a liquid. The molecules in a drop of water attract each other weakly.
What is a stretched membrane? The stretched-membrane concept is a potentially low-cost and structurally efficient method of attaining and supporting a large, optically accurate surface for heliostat applications. In this concept, a high-strength structural film coated with a highly reflective surface is stretched uniformly on a torroidal frame.
What is the tension of the surface film of a liquid caused by the attraction of the particles in the surface layer of bulk of the liquid? Surface tension is the force that causes the molecules on the surface of a liquid to be pushed together and form a layer. It is the tension of the surface film of a liquid caused by the attraction of the particles in the surface layer by the bulk of the liquid, which tends to minimize surface area.

how do particles in gas behave?
In gases the particles move rapidly in all directions, frequently colliding with each other and the side of the container. With an increase in temperature, the particles gain kinetic energy and move faster.

If you notice it scratching the scratching pole instead of your sofa, reward it. Your cat will quickly learn the difference between good and bad behavior.
what causes gases to behave non ideally?
At relatively low pressures, gas molecules have practically no attraction for one another because they are (on average) so far apart, and they behave almost like particles of an ideal gas. At higher pressures, however, the force of attraction is also no longer insignificant.

how does a current loop behaves like a magnetic dipole?
