Oh, wow, oh, oh, wow, oh, wow, oh, man.

Oh, wow. Hello, you're listening to The Science of Everything podcast, episode 31, solutions and mixtures.

I'm your host, James Fodor.

In this episode, we're going to look at an analysis of liquids and their behavior when mixed with other substances,

including a look at solutions, mixtures, colloids, and suspensions, all of which are various types of liquids mixed with other substances.

Although mostly we'll look at solutions, because they're the ones that come up most often

in chemistry and other locations, including an examination of topics including solubility,

saturation, molarity, and the formation of bubbles, which is actually quite interesting.

Okay, so before we get into those details, we'll start off with an introduction of,

and look at the question

of what is a liquid. Now, from previous episodes, or general knowledge, you may know that liquid

is one of the three classical states of matter, the other two being gas and solids. Liquid is in

sort of temperature range between gas and solids, so it's sort of in the middle range. However,

liquids, pure liquids are relatively rare on, at least at Earth's temperatures that are found on Earth's surface, like around standard room conditions. Water is one of the few substances, few substances that is a liquid at room temperature.

Liquids form when the intermolecular bonds between the molecules holding a solid together break apart and

therefore the molecules are able to begin sliding past each other. However, in liquids,

the intermolecular bonds don't completely break apart. So they sort of mostly but not quite break

apart so that the molecules are still held together to retain the basic shape. The difference between the liquid

and aghast though is that in aghast the molecules, the bonds between the molecules completely

break apart and the molecules are free to just move completely separate from each other, whereas

in a liquid, the molecules are still held together by weaker bonds, but they're still held together

to some degree, and so the molecules merely slide past each other.
