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.
- 04:14 “which says 143 degrees Celsius. Temperature in Kelvin equals to temperature in degrees Celsius plus 273. As I've seen before this present slide, then giving that temperature in degrees Celsius is 148 degrees Celsius, the...”
- 03:26 “the higher the temperature. E volume increase, temperature we also increase, provided temperature remains constant. And at KV temperature, which is absolute temperature, we are giving it to be at -273 degrees Celsius. An...”
- 14:43 “Celsius, to be combated to Kelvin, you are 273, then you obtain 279 Kelvin. P2 from the question at standard temperature of pressure is 76 mm mercury. And V2 is what we are looking for. T2 is temperature at standard. Tem...”
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.
- 14:07 “So, this one, it will continue absorbing more, continue taking in more of these solutes. Now, even when the temperature, if I, when you increase the temperature, so that's when it will even absorb more, so that's a solid...”
- 15:44 “understandable, so this is very clear. So, for potassium iodine, at zero degrees Celsius, as you can see now, you see that the solubility is one rattety, as you can see there, it's one rattety more per DMQ, all right, as...”
- 34:21 “saturated solution, this solution in low is saturated, meaning that for me to know the total mass here, that is actually inside this solution, so in the presence of all dissolved solution, so we need to add this one to t...”
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
- 02:38 “Water consists of two major elements, hydrogen and oxygen, and the chemical formula is H2O. The boiling point for water is 100 degrees Celsius. Now, when you boil your water in the kitchen, at the point where you begin t...”
- 18:07 “When you mix it in cold water, you will notice that it will not dissolve well. And at that point, you are having a colloid. Colloid is a mixture in which one substance of microscopic dispersed insoluble particles are sus...”
- 03:24 “The elements in water are hydrogen and oxygen, and the structure is H2O. And they are existing in gaseous form. It can exist in liquid form, and it can exist in the solid state. Water can exist in liquid form. It can exi...”
Fundamental and Derived Quantities
This lesson covers the definitions of fundamental and derived quantities in physics. It explains how fundamental quantities serve as the base for deriving other quantities and the importance of measurement in physical science.
- 04:44 “Sometimes can be measured in gram, but the standard unit is the kilogram, which is KG as symbol, the time, which is a function of everything, is measuring second, and the symbol is what is of X. The temperature of an obj...”
- 12:39 “So these are the common ones that you always find in the study of our physics, but there are other ones in the area of heat, electro dynamics, AC circuits, wave, light and light. In SI units, derived units are often give...”
