Gas Laws Overview
This lesson covers the basic gas laws including Boyle's Law and Charles's Law. It explains the relationship between volume, pressure, and temperature of gases, and introduces the Kelvin scale for temperature. The general gas equation PV = nRT is also discussed.
- 00:10 “Good day everyone, my name is Adekunle, I'll be teaching you chemistry and the topic for today is gas loss. The first gas loss we are going to talk about is boy's law. According to the about board in 1662, it says the vo...”
- 15:32 “so we obtain V2 equals P1, V1, T2, all over P2 over T1, P2 over T1, then V2, putting all the values in, you have 758 times 35 times 273, all over 76, and then T1 is 279. You obtain, at the end of the if you put your capi...”
- 02:39 “plot the graphical presentation of Boyz Law forming. Chast Law is the next law. This shows the relationship between volume and temperature. And Chast Law states that the volume of the giving mass of gas is directly propo...”
Solution and Solubility
This lesson covers the concepts of solution, solute, and solvent. It defines solubility and explains different types of solutions, including saturated, unsaturated, and super saturated solutions. Factors affecting solubility and calculations related to solubility are also discussed.
- 19:52 “the pressure has negligible effect on the solubility of liquid and solid solutes, but it has a strong effect on solution with gaseous solute, okay, now this is apparent every time you open the soda can, all right, the hi...”
- 26:58 “actual to express in more PDNQ, now already here you have to bring out what is it that we're giving, here, we are giving basically the mass, all right, then now we're giving the volume, take note of that, all right, we'r...”
- 19:02 “this before, even from the chart that explained that before, all right, of a given solute in the given solvent, typically the pace of temperature, for many solids, so dissolve in liquid water, solubility tends to corresp...”
Oxides of Carbon
This lesson covers the two types of carbon oxides: carbon monoxide and carbon dioxide. It explains their formation, characteristics, and methods of preparation in the laboratory. The lesson also defines the term allotrope and discusses the economic importance of these oxides.
- 04:42 “So, at the end of the day, you are going to have carbon two oxides. So, as you can see, in this equation, so, carbon two oxides, it's actually from here, alongside with water, okay? So, now, that's for that. Now, another...”
- 07:02 “to take is carburetor oxide. But alongside, carburetor oxide is also formed. Like you can see in this equation here, this equation is showing us how that happens. So, then this one is a ethythic dioxide. So, that is actu...”
- 20:54 “Basically, when it's raining. So, what we have most time is actually the form of acid that is formed, there is a weak acid. It's all called carbonic acid, basically, okay? Which has a pH of five, okay? That, this equatio...”
