Compare homogeneous and heterogeneous equilibria.

So the differences between heat and temperature so heat think we can either represent with a capital Q or a lower case. Q. You'll see both ways, but it's always que, um, heat here. Think of it is energy where the easiest way to think of it is remember, this is gonna be in units of, like, jewels or kill a Jules. Something to do with the unit of Energy where Jewell is. Ah, sort of the base unit here. Right. Uh, compare that with temperature, which is usually a capital T. Um, this is a way to measure energy Temperature is going to be a cling degrees Celsius, Kelvin. Something like that. I noticed that the units are different here. Temperature isn't a isn't energy all by itself. But it's a way Teoh measure energy. And the easiest way to see that is let's think about our ah, our calor caliphate calorie McGary equation. So we've got que here heat is going to be equal to the mass times the specific heat times the change in temperature. And so by measuring the change in temperature when you measure this, what you're actually measuring is your measuring the heat flow right, So change in temperature is a way for you to measure the energy change of a system. Um, another way to think about it is in terms of let's talk about the kinetic energy of a system so kinetic energy average is going to be equal to three halves times the number of moles, times to gas, constant times the temperature of the system again and sort of the same thing right where you have energy on the left and you have temperature on the right side of the equation, where the temperature when you measure the temperature that tells you about the energy of the system. It is not the energy all by itself, though it is a way to measure.

Good day. The topic is about solutions and we may also include here or touch the mechanism when which solutions are formed. Now solutions I composed of solute and solvent salute comes in smaller amount than the solvent in the formation of a solution. It must be that the salute which may be a gas or maybe gas liquid or solid or any of those three phases. It must be dissolved in solvents. It must be kept dissolved in solvents since can also be that well it is dissolved, it may escape. So that happens usually for gases in liquids are solid. So in that case you don't have true solutions. And uh so it follows that the solute solvent interaction is very important that the act of dissolving salute insolvent is what is called the solution. Yeah we say that this solution is the process shit in which salute is dissolved insolvent. In other words it is the process of formation of solution. When we view at view this the process uh in down to the molecular level, you can imagine solute solvent interaction. So the process, or now we see the phenomenon where in the solvent particles uh surround the solute particles is called the salvation process. And specifically, if the soul event is water, then the Salvation process mhm. Is technically termed as hydration. Uh What? Right? All right. So we have just defined these three terms here that are associated with the formation of solution, so I help. These are all clear well.

Sublimation is the process where cell that moves directly to the guests, their heart skip still a quick fix. Example. This will be dry. Ice deposition is similar in which it is a gas, moving directly to a solid once again skipping the liquid state. Example that this would be frost. So, um, liquid or gas Castro's moisture becoming a sell it on your car for sale in sublimation. Energy is used in this process to move from a salad to guess all in deposition energy is released in the process.

Been talking about sublimation and evaporation were are involved cases talking about the changes of a state matter with the ending result being being in its gaseous face. But the difference is in what manner it is moving from a salad into into a gas, a fever. And so if we think about this most of the time, our normal idea will be happening. But we have a salad that would somehow turn into a liquid, and they went to impound turn into a paper and this could be done either with or without a key. And so when we talk about evaporation, we're thinking of some sort of liquid being turned into a paper. Usually think about water and for evaporation. This is with that heat. This is up just the natural process off moving from liquid to shape her guests what we talked about sublimation. We're thinking of a salad being transferred directly into vapor. So in this case, you completely missed liquid phase and just jump straight into, um, they cast the vapor. So example ofs information would be compound situation give or frozen carbon dioxide, in which there is no need to intern the liquid face. It was jump straight from salad
