Is a change in phase a physical change or a chemical
change? Explain.

Question. Number 71 wants you toe lift three properties of a Covalin compound in solid phase. If it's a Covalin compound in a solid phase, we can just describe some of the general properties associated with the Covalin compound without knowing exactly what it is because it's in the solid phase. Weaken state. Several properties general properties associated with just solids. It could be an Ionic compound also, but in this case it's a co violent. But regardless, because it's a solid, it will have a defined volume. It will also have a defined shape. It'll be non compressible because it's a Covalin compound. There will be molecules that are present, that air fixed in position, and these molecules will be fixed in position or held together due to inter molecular forces different from an ionic solid molecules air not present. We have ions present and in an ionic solid. The ions are held together not by inter molecular forces but by electrostatic forces

Hello. Today we'll be talking about Chapter 14 Question 58 which asks us to consider a cull oId made up of a gas dissolved in the liquid. And so an example of that would be whipped cream where, if you actually make whipped cream, you combine your cream and everything else your sugar et cetera in your bowl, and it's better. Everything else all of those tasty, tasty things, and then you whip it with your whisk. He's a little poorly drawn whisk, and you do that over and over, and as you're whipping it, it starts to stop being a liquid, and it starts to kind of become a little bit foamy. And what's happening is you're actually taking air the gas air and you're basically capturing little pockets of air. That's an air pocket surrounded by kind of blobs of cream. And you're doing this on a very, very small level. And so the result is that you kind of have a foamy blob that kind of melts away in your mouth because a lot of it is just a WR, and so what you're doing when you make this kind of a colleges, you're literally forcing the air to dissolve into the cream mixture the cream solution. And so hopefully this gives you a little bit of a better idea of what a cholera it is and how we actually encountered them and maketh, um, in everyday life.

Listening the phase transition in each of the following and whether that phase transition is either eggs, ophthalmic Randall thermic. For a when ice is heated, it turns into water. This piece transition is melting and melting is an endo thermic process. Yeah. For B What clothes dry on a warm summer day? This phase transition is evaporation. Yeah. And evaporation is an MBA thermic process. Mhm. Yeah. See frost appears on a window on a cold winter day. This is an example of condensation uh for us to the assault. So this would be deposition and this will be an economic process. And for d droplets of water appear on a cold glass of beer. This phase transition is condensation, which is an exotic process.
