Gas Laws
The lesson covers the relationship between volume, temperature, and pressure of gases. It explains Boyle's Law, Charles's Law, and the general gas equation PV = nRT. Students will learn how to perform calculations involving these laws and the importance of using Kelvin for temperature.
- 19:33 “That number of moves N equals to mass over molar mass. So between the ideal gas equation, we have PV is equals to M, small letter M over capture letter M. That is substituting this number of moves. Sometimes in the exam,...”
- 18:44 “volume is in DMQ. Well, whenever you are solving any calculation involving ideal gas equation, the gas constant to be used will be given to you. Ideal gas equation PV is equals to NRT, that you remember that number of mo...”
- 17:57 “Ideal gas equation PV is equals to NRC. Where R is a gas constant giving us 8.31 views per kilo per mole or 0.82 atmosphere DMQ per mole per kilo. The value of R to the use depends on the units of parameters given. Use 8...”
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.
- 09:02 “temperature, and non-ball of moves, or mass. And then, combined with Avogado's flow, we say the equivalent of four gases at the same temperature and pressure, continue the same non-ball of molecules. Also, taking note of...”
- 11:26 “understand the next examples. Since 1.5 more of an ideal gas at the temperature of minus 15 degrees Celsius, and pressure of 2 atmosphere, what volume in DM cube really gas occupies at that temperature? Given the value o...”
- 06:42 “proportionality and it puts equation. At the other day, you obtain K to be equals to Vp over T, which at the end of the day, you are going to obtain P1, V1, all over T1 equals to P2, V2 over T2. The general gas equation,...”
Electric Cells and Current Electricity
The lesson covers the types of electric cells, including primary and secondary cells. It explains the concepts of electromagnetic force, current electricity, potential difference, and resistance. The arrangement of cells in series and parallel is also discussed.
- 29:45 “Remove this proportionality sign, we have z q. q is equal to what? The electricity, which is what? i, c, y, z is the constants, which you have that word, m is equal to z, i, c. Nice. We have it here. Now, the second law...”
- 30:40 “Now, z is a constant of the proportionality, which is known as what? Electrochemical equivalent, which is called the e, c, e, of a substance. It is the mass of that substance deposited by one column of electricity in a p...”
- 36:09 “Now, let's get the internal resistors, internal resistors, internal resistors, which will give us 0.5 plus 0.5, will give us 1.0 ohms. Now, let's get the total voltage, total voltage, total voltage will give us V1 plus V...”
Revenue Types
This lesson defines revenue and explains its three main types: total revenue, average revenue, and marginal revenue. It covers how to calculate each type and their relationships to production and sales.
- 05:10 “So, let's get the words, the solution to these words, so this interesting question won't have to the other. Look at the board, here you have what, P is on the wall, it's first on the CR, remember the formula I give to us...”
- 19:02 “Total revenue is what? 30. Minus total cost is what? 25. Can you see? 25. So the difference between this and this is what? Five. So ladies and gentlemen, this is our profit. Can you see? Very easy. See R minus CC. That i...”
- 10:35 “so that is how you guess your words, the value of P, is not more than that, okay, so that's this for your P, and if you look at words, the illustration, you will see that's exactly what we are doing. so the next one is w...”
