About :
Liquids, along with solids and gases, are one of the 3 basic states of matter. In order not to confuse the terms, let us recall that the word liquid refers to liquids and gases together, because they can flow. However, liquids (water, oil, blood) have the ability to clump together into drops, hence liquids. Molecular structure Liquids have their molecules far enough apart to be able to move freely throughout the volume of the liquid. They are not bound in solid structures, such as crystalline solids. However, the kinetic energy of the molecules is not so high that they break free from interaction (as in gases) and therefore liquids have a constant volume. Properties of liquids We can observe the following properties of liquids: They can flow, they do not have their own shape and they copy the shape of the container in which they are located. They have a constant volume, they are almost incompressible Diffusion takes place in them (spontaneous penetration of particles of one substance between particles of another substance), but more slowly than in gases Heat spreads in them by flow (warm liquid rises up and cold liquid down) The mass of the liquid creates a surface that has different properties than the rest of the liquid. A small amount of liquid (e.g. in a spray bottle) creates drops Ideal vs. real liquid A real liquid exhibits viscosity (internal friction) when flowing. This can be clearly seen, for example, in honey, which stretches rather than flows. Furthermore, it is also compressible to a limited extent, but somewhat. For our calculations, we will use the concept of an ideal liquid (works well for water). This takes into account that the liquid is not viscous and is completely incompressible (has a constant density).
