A liquid is a nearly incompressible fluid that conforms to the shape of its container but retains a (nearly) constant volume independent of pressure. As such, a liquid is one of the four fundamental states of matter (the others being solid, gas and plasma). A liquid is made up of tiny vibrating particles of matter, such as atoms, held together by intermolecular bonds. Water is, by far, the most common liquid on Earth. Like a gas, a liquid is able to flow and take the shape of a container. Most liquids resist compression, although others can be compressed. Unlike a gas, a liquid does not disperse to fill every space of a container, and maintains a fairly constant density. A distinctive property of the liquid state is surface tension, leading to wetting phenomena.

A liquid is a state of matter in which a substance changes its shape easily and takes the form of its container, and in which the substance retains a constant volume independent of pressure. As a result of this, a liquid does not maintain a definite shape, and its volume is variable. The characteristic properties of a liquid are surface tension, viscosity, and capillarity. The liquid state has a definite volume, but it also has a definite surface. The volume is uniform throughout the whole of the liquid. Solids have a fixed shape and a definite volume, but they do not have a definite surface. The volume of a solid does not vary, but the volume of a liquid may vary.

Which of the following is …
okay for this one. We have aluminum hydroxide as well as sodium hydroxide. We want to show the equation of how they would react together and solution. So let's do it out, then aluminum hydroxide and then know that in solution, this sodium hydroxide is going to associate right away. It's a strong base, so the sodium ions aren't going to really matter much. But the hydroxide ions will react with aluminum hydroxide and aluminum's um, aluminum hydroxide is able to accept lone pairs, and O. H negative has plenty of those. And so they would just come together and you get aluminum hydroxide with out but four of them and then the negative charge. But what's happened here? Well, aluminum hydroxide X like an acid, but only under this Louis definition of an acid. So what we saw was the Lewis acid base reactions, and there you go
