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.
- 00:02 “Good day, everyone. My name is Charles Christopher. I'm the chemistry teacher, and I'll be taking you on the topic solution and solubility. Now, before I begin, I would like to give you the objective of the lesson. Now,...”
- 00:47 “Now, the students should be able to also define the following terms, saturated solution, unsaturated solution, and super saturated solution. And also be able to leave the factor that affects the solubility of the solute...”
- 06:15 “Now, let's not know the difference between a true solution and a colleta solution, all right? A true solution is for when solute particles dissolve in such that they are able to get in between the solid particles, take n...”
Water and Its Properties
This lesson covers the composition of water, including its chemical formula H2O. It explains the physical properties of water, such as its states (solid, liquid, gas), boiling and melting points, and its ability to dissolve various substances. The lesson also discusses the importance of water in liv
- 16:30 “A solution is a special type of homogeneous mixture composed of two or more substances. An example that you have in the house is salt. You place your salt in water, you mix it together with the spoon. You will notice tha...”
- 15:34 “However, this will result into a solution. When the chalk is placed into a water, you have a chalk solution. So, solvent, example of a solvent, is water. Now, in the picture, you see an example of solute. It is like a po...”
- 00:10 “Good day, everyone! My name is Mr. Ife and I'm your basic science instructor. Our lesson today is "Says, Water, and Rustam". A quick round through the objectives. At the end of the class, students should be able to expla...”
Translating Word Problems into Equations
The lesson teaches how to translate word sentences into mathematical equations. It covers the use of variables to represent numbers and how to express word problems as algebraic expressions. Students will learn to solve simple equations and check their answers.
- 19:25 “We've come to the end of today's class. Thank you so much for watching. My name is Dorkas Aoye, till next time.”
- 16:13 “cost 20 more. So noodles is X plus 20. What are the cost of 4 such as of milk and 8 such as of noodles? So for 4 such as of milk, 4 such as of milk, that's 4, say 4 milk, 4 milk such as X and 4 places, X in 4 places, whi...”
- 00:02 “Hello, my name is Dorcas Awaye. I'll be taking you mathematics today, and today's topic is algebraic processes, talking about simple equations. At the end of today's teaching, you should be able to translate word sentenc...”
Similar Shapes
This lesson covers the identification of similar shapes such as triangles, rectangles, squares, cubes, and cuboids. It explains the criteria for similarity, including proportional sides and equal angles. The lesson also includes methods for enlarging figures using scale factors and calculating lengt
- 25:22 “these 2, if it cannot be in this form then your answer is wrong, now the last part is applying it to water problem, how do we apply it to water problem, how using your scalar factor to solve a problem, olatical wants to...”
- 28:50 “We said that solution. A scalar factor is that of the longest. The longest, the first side given, the first side given is the wall. The longest, remember, over longest of the beak, those sides that are given, and the lon...”
- 23:43 “triangle, BAC, that's remember from the scalar, from the scalar that we meant comparison, now you will see why the scalar of 2 can also be checked, so that gives me 384, the bigger one, over 96, now if you look at 96, so...”
