Just a note about the glass being a liquid debate: there’s this idea that old stained glass windows are thicker at the bottom because the glass has flowed down; this is a myth. Old windowpanes are often thicker at the bottom, but that’s because the techniques to create very flat glass didn’t exist, so they’d put the thickest part of the pane at the bottom for stability. Glass is more viscous than lead; if the panes were old enough to start flowing down, the lead lining around them would be a puddle on the ground.

That story about old windows is the origin of the argument but there is a lot more behind it than that. I study materials science and this came up in one of my lectures a while ago. From what I remember of when my professor brought this up at uni, the way glass is structured means it's possible for glass to flow (theoretically), but the time it would take for an observable change is insanely long meaning it's pretty much impossible to verify experimentally. By the way, if it is a liquid it is extremely viscous to the point it appears solid hence all the other properties.

Could you make a series on cooking eggs? I always hear it's one of the basics you need to know how to cook with before you even get into making anything else, and I want to know how I can make better eggs.

Glass is definitely a solid, an amorphous solid, meaning it doesn't have a crystal structure (it's kinda blobby on a molecular level), and it doesn't have a well defined melting point, but rather a melting range. Butter is the same btw. You'll often hear people say glass is a slow moving liquid because very old houses have windows panes that are thicker at the bottom, but this is actually just an artifact of how window glass used to be made. Sometimes the thick section is on the top if the builder put the pane in upside down

@LiborTinka

Sometimess the two layers form very slowly because the liquids have very similar densities. And sometimes the layers can even switch provided one layer contains dissolved solids making it heavier (more dense). In chemistry, resolving emulsions can be as difficult as forming them. Sometimes people add salts to the water precisely to push the oil or whichever different nonpolar compound out of it. Separating clove oil extracted by steam distillation is one example.

For anyone interested, one definition of a colloid is 'two phases mixed together, where one is the continuous phase and another is dispersed within it and the dispersed phase has at least one dimension between 1-1000 nm', some examples of colloids you might not expect, deodorant, ice cream and stained glass. Stained glass contains metal nanoparticles dispersed in glass and often different sizes of the same metal nanoparticles often give you different coloured glass!

I don't watch Adam's videos for food knowledge anymore, I watch for the segues. That sponsor segue was on POINT.

that honey segway was absolutely legendary

For those curious about his reference to glass: a window pane, after many years, will be thicker at the bottom than it is at the top. This would imply that glass is a viscous liquid, since it's flowing downward with gravity. Just... very very slowly. I don't know if there's an consensus on if it qualifies as a liquid or not, but it's been under debate for a long time. That's all a naming technicality though. It's like "is water wet."

A phenomenon of practical importance I hope you'll explore in your 201 video: temperature-stability of emulsions. You mentioned the role viscosity plays in forming emulsions, but if most liquids are more viscous at lower temperatures, and more viscosity means a more stable emulsion, why do I need to heat a mixture to emulsify with corn starch for example. And why does the vinaigrette that I've stored in my fridge stay separated no matter how hard I shake it, until it warms up? These examples appear to contrast with the idea that higher viscosity = more stable emulsion.

@Mavromichales

2 жыл бұрын

Temperature doesn't just affect the viscosity but also the surface tension (or more precisely the interfacial tension in the case of two liquids) with higher temperatures corresponding to lower interfacial tension as the molecules are bouncing around more and so are not as strongly attracted to like molecules. This reduction in surface tension is also what surfactants like lecithin are doing by interacting with both the polar and nonpolar liquids at the interface. So in the cases you mentioned, while changing the temperature has competing effects from influences on viscosity and surface tension, it would seem the change on the surface tension has the greater impact.

So much nitty gritty detail about how the world behaves that most people don't take the time to understand. My friends lovingly describe me as a pedant, and this is exactly the kind of information I love learning. Thanks for the video, Adam! This one is great!

As a college student studying chemical engineering, I am incredibly happy you decided to do a deep dive into emulsion!

Adam, you actually put this videos out at a quite perfect time. I'm studying ecotrophology (nutrition and food science) and currently we're talking about lipids, emulsions obviously being a relevant part of this topic.
