Many a time many Students raised a problem that if a single teacher can’t teach every subject how can a single student study all subject…Alakh sir proved them wrong🔥🔥
sir ye chapter mere liye boring tha i even slept in my 1 hour classroom lecture of this chapter but you have made this chapter so much interesting that i spend hours solving numericals of this chapter thanks alakh sir you are the best santa for me sir god will make you and your family very happy and prosperous

@@ABHICHAY how ironic , if you read carefully they literally said "I feel everything without feeling bored with some practice also" if they wrote sum , which doesn't makes sense.
Literally, from 00:00 to 51:00, Alakh sir was playing with addition multiplication, division & formulas. It was like a miracle from his whiteboard and that black marker. I was really astonished that Alakh sir is the God of physics and also has the greatest grasps over the knowledge and concepts in chemistry too.
At 31:35 the formula of force exerted is given but the derivation done must be wrong as F=dP/dt where dt is the time taken for the collisionor the contact time with the wall what was given there as time was the force between 2 sucssessive collisions(one after the other) in which acceleration occurs only at one point that is only at the instant of collision so dp/dt= mdv/dt or ma (F=ma) acceleration is happening only during the collision not throughout the movement of the molecule through the container. Any way great lecture east or west Alakh pandey is the best.
Kashif Farhaan sahi hai Bro yeh chemistry me kuch bhi ho sakta hai. Although some chapters are good. But chapters like ideal gas,ionic equilibrium work only on wierdly derived formulas.
53:30 - Sir, you said that it is only valid in monatomic gas but O2 is a diatomic gas... So it was not happen but you do it by that method... So how was this possible...
19:38 we know that gravity on an object doesn't depends upon mass. But here, sir said that gas molecules are so light that gravity has no effect on gas molecules.
Acceleration due to gravity does not depend on mass....but force of gravitation depends upon both mass of the earth as well as mass of the body on which gravitational force acts F= (G m1 m2)/r^ 2

Hello sir I study at kota (Resonance) and sir I must say your videos are a great help for clearing doubts, in fact u r better than most of the faculties over here. Thank you a lot sir for your videos
Yes you are right ....

Sir in last question we have taken time taken for one collision = 2l / Urms
But sir in the derivation we used time taken = 2l / Ux1
Why ?
I have same question.
U r ?
😉
Yes,I have a same doubt
Because in the derivation we are finding force due to 1 molecule but in this ques we are considering all the molecules so we have to take rms velocity

Last question !
--> PV = 1/3mnV²
--> for one mole
RT= 1/3mnV²
mn = total mass of gas = 4g
--> RT = 1/3(4)(20)²
Substituting R value we get
--> T = 64.14K
Hope this method will be the easiest
Please check this☝️
But mass should be in kg right?
@@debomdas6224 not neccesary
@@debomdas6224 we actually need atomic mass and he wrote gram atomic mass so we just need the numeric value

56:30 the question must me the temperature increases by not changes sir change to decrease bhi ho sakta hai
Kyuki bhai mention nhi kiya toh sir ne assume kiya hai ki temperature increase huwa hai

Literally, from 00:00 to 51:00, Alakh sir was playing with addition multiplication, division & formulas. It was like a miracle from his whiteboard and that black marker. I was really astonished that Alakh sir is the God of physics and also has the greatest grasps over the knowledge and concepts in chemistry too.

At 31:35 the formula of force exerted is given but the derivation done must be wrong as F=dP/dt where dt is the time taken for the collisionor the contact time with the wall what was given there as time was the force between 2 sucssessive collisions(one after the other) in which acceleration occurs only at one point that is only at the instant of collision so
dp/dt= mdv/dt or ma (F=ma) acceleration is happening only during the collision not throughout the movement of the molecule through the container.
Any way great lecture east or west Alakh pandey is the best.
Kashif Farhaan sahi hai Bro yeh chemistry me kuch bhi ho sakta hai. Although some chapters are good. But chapters like ideal gas,ionic equilibrium work only on wierdly derived formulas.

19:38 we know that gravity on an object doesn't depends upon mass. But here, sir said that gas molecules are so light that gravity has no effect on gas molecules.
Acceleration due to gravity does not depend on mass....but force of gravitation depends upon both mass of the earth as well as mass of the body on which gravitational force acts
F= (G m1 m2)/r^ 2
