- 00:42 Relation between root mean square velocity and absolute temperature
06:04 Expression for Kinetic Energy of a Gas
09:25 Kinetic energy per unit volume
12:38 Kinetic energy per mole
15:34 Kinetic energy per molecule
16:56 Kinetic energy per unit mass
21:14 Example: 3.1 Obtain the mean free path of nitrogen molecule at 0 °C and 1.0 atm pressure. The molecular diameter of nitrogen is 324 pm (assume that the gas is ideal).
28:56 Example 3.2: At 300 K, what is the rms speed of Helium atom? [mass of He atom is 4u, 1u = 1.66 × 10^-27 kg; kB= 1.38 × 10^-23 J/K]
35:35 Problem 11. Calculate the ratio of mean square speeds of molecules of a gas at 30 K and 120 Κ.
38:10 Problem 12. Two vessels A and B are filled with same gas where volume, temperature and pressure in vessel A is twice the volume, temperature and pressure in vessel B. Calculate the ratio of number of molecules of gas in vessel A to that in vessel B.

LOVE YOU SIR❤️🩹
Thanks a lot for your love and support
@@venkypunjabi_physics 🤍
@@venkypunjabi_physicsThanks To You For Giving Rich Content In Free of cost🙂↕️😌
Most welcome
Sir R/NA=kb ...This formula is from which chap...As My 11th Was Wasted...So idk The Formula Is from chap of 11th
Chemistry me sikhate hai yeh
