Sir, you have cleared the most confusing thing in the whole syllabus. Even teachers (School & Even famous teachers in Kota too) are not clear on this part, whenever we ask them they say learn that signs are opposite in Phy & Chem or they say some random stuff to confuse us. Today i got to know the real truth. Thanks Sir ❤

Summary of the video: 1) Work done on the gas contributes to increase in internal energy. And work done by the gas contributes to decrease in internal energy. 2) "Work done by gas is positive in physics whereas negative in chemistry" This is a false statement. Work is a fundamental quantity and it is same everywhere. 3) If Work done on the gas is positive, then it implies that work done by the gas is negative and vice-versa. This creates the illusion stated in 2). Sir, please correct me if I am wrong. Btw this video was most needed, you cleared fundamental confusion.

The simple explanation is in physics and engineering the main focus is on how much heat can be converted into work whereas for a chemist the domain of interest is how much heat can be converted into internal energy . An engineer would be more than happy to see as much of heat converted into work in contrast chemist studying molecular properties would want as much of heat converted into internal energy as possible .

Why can't we just argue simply that if work is done by the system then ∆V = V2 - V1 is positive because V2 > V1 So P∆V will also be positive. Similarly if work is done one the system then ∆V = V2 - V1 is negative because V2 < V1 So P∆V will also be negative. Please let me know about it because in this case there will be no need to consider the scalar product of Force and Displacement.

Sir, I have a question related to the Charles's law and cosmology. From Charles's law, theoretically it is possible that the volume of any gaseous substance can be zero at the absolute zero temperature. So if we imagine a gaseous substance at absolute zero temperature, it will have some mass in a point (as the volume is zero). At this condition, can we consider the massy point of the gaseous substance as the singularity of black holes or the singularity during the Big Bang?
@dr.aryanjangir07
@dr.aryanjangir07 10 ай бұрын
Charles's Law is applicable to gases within a specific temperature and pressure range. At extremely low temperatures near absolute zero, other factors come into play, including quantum effects. The singularity in black holes and during the Big Bang are concepts that involve extreme conditions where our current understanding breaks down, and we need more complete theories, such as quantum gravity, to describe them accurately.

Eg.Find ∆U if gas absorb 50J heat and gas does 20J work PHY :- Q=∆U+W 50=U+(20) ∆U=30J CHEM:- ∆U=Q+W U=50+(-20) ∆U=30J I hope u understand
@hcverma2928
@hcverma2928 10 ай бұрын
No need to remember any formula. You have given 50 J of heat to the gas. So you increased 50 J of internal energy. The. gas does 20 J of work on you. So the internal energy of the gas is decreased by 20 J. In the whole process the internal energy is increased by 30 J. Formula based learning should be avoided.

Hello, my name is Aryan and I am a student in 12th grade from Sikar, Rajasthan. I have a question that I was hoping you could help me with. If we define a wave as a disturbance in a medium, then why do we refer to light as a wave even though it travels through space, which is considered to be medium-less? If there is no medium, there should be no disturbance and thus no wave. Thank you for your assistance.

Mechanical waves are defined as disturbances in a medium . In general wave is a phenomenon that can transfer energy and momentum via periodic variation of some quantity . In case of string , varying thing is displacement from original length . In case of sound waves , varying thing is air pressure . In case of light , varying thing is electric and magnetic field . Yes , electric field and magnetic field is varying and travelling as a electromagnetic wave . Thinking it without no medium is a bit tough even for Maxwell . He himself thought of EM wave as stress and strains through a hypothetical medium of ether . But in reality , there is no medium needed to vary magnetic and electric fields .

Bro light is an EM wave And EM waves don't need any medium to propagate And by the way light shows dual nature... sometimes it behaves like a wave and sometimes like a particle...till now its a dilemma Some phenomenon like diffraction polarisation can be explained by wave nature of light while refraction reflection and related phenomenon can be explained using particle nature

Hello sir I am Aryan Gupta I am studying in class 9 I wanted to ask a question from physics from work energy chapter which is when we define energy it is define as ability or capacity to do work and when we define work like that Work is the transfer of energy by a force acting on an object as it is displaced. When I read this I think it is absturd How is energy and work is interlinked like that and why don't these definition can be studied separately. I think it is question of which is more basis force or energy. My humble request pls 🙏 explain this thing in deep or make a video on that Thank you Yours concept of physics book follower and your yt channel subscriber

sir my first question--- in classical mechanics we can solve every question from newton law of motion a subset of these questions we can also solve by energy conservation which lead to clear that energy conservation should be a result of newton laws but i have tried to find derivation of energy conservation by newton law of motion but i only found derivation which is given in some specific context(not in general case). my second question-- when we look in quantum mechanics conservation laws(energy conservation and momentum conservation) are valid even if newton laws are not valid(but how physics community accepted that. i have a idea with which you can clear our this kind of question with minimal efforts from you i am giving this idea in last paragraph please try it or suggest some resource which already done this ) idea is to create some recourses where we get the all pure physics happenings(not including things like how we found the speed of sound because that is formula which is for very specific context not useful in understanding of theoretical physics but include any experiment if it helps in understanding of theocratical physics) to respect your time we only need name of topic and findings in sequence of time of finding this help us in get to know how physics really developed with time and why physicist defined some particular quantity.

Answer 1 - Every problem can be solved both by Work-energy theorem and Newton laws of motion . The one we use depends on the information given in question . You can easily derive energy conservation or more generally Work-Energy theorem by newton laws . You can search Derivation of work energy theorem on net and see . When only conservative forces are present . Then energy conservation happens , a sub case of Work -energy theorem . Answer 2 - You can get a timeline on wikipedia . Also about the part where u said "How could physics community accept that!!?" . As long as their is empirical evidence for their theory or claim and also has a satisfactory framework . Science will accept that . When newton suggested that fallling apple and moon revolving are same phenomenon he gave evidences for it , so science community believed it .
