I have never seen a professor have this much passion on teaching a subject. He's clearly a legend and he already earned my respect long before this first lecture ends. What a man to look up to as an engineering student
Please don't spread this misguided and false information. A faculty from IIT Kharagpur named Joydip Bhattacharjee died while saving his 4 year old son not him. Here's link of one of the many articles that I have read : www.huffingtonpost.in/2017/08/27/iit-kharagpur-professor-joydip-bhattacharjee-drowns-trying-to-save-4-year-old-son_a_23187479/ Also, a student from IIT Kharagpur named Som died in road accident, not him
If you guys facing issue with audio on one side only, And you are on android then it may help, it worked for me 1. Go to mobile setting 2. Search for audio (Mono audio for mi users) 3. ENABLE that mono audio option. Thats it .👍
Prof. Som was one of the finest teachers at ME Dept in KGP. He had crystal clear concepts and animated & interactive delivery. One can see that energy level here also inspite of all the constraints imposed by the recording process.
For all the people who are saying that this lecture is useless i want to say that in this video he just wants to tell the purpose of studying thermodynamics and of what it is actually about.This video can create your interest in the subject.Thermodynamics is one of the most beautiful sciences and each and every process and event through out the universe are governed by laws from this basic science.He introduced the subject in excellent way.
I have gone through the whole lecture series and I can bet this is the best lecture series in basics of thermodynamics. Thanks for such a valuable content.
Extremely indebted to Prof SK Som. Have watched his lectures repeatedly while preparing for GATE. Helped me in cracking Gate. Felt sad when i came back here to see his video and saw comment that he is no more. Prof SK Som will be remembered by every engineer who has attended his classes. RIP!!
@@muchen597 at 0:30 it says 2004. even if her father was 18 (1st year of engg) when he 'viewed' it, which means 2 years ago, when this was commented, her father would be 33 years old which still is strange
Profesor S.K. Som is really a True Legend of Thermodynamics.. For those.. who really dislike Thermodynamics, gonna fall in love with this Subject.. Being a student of B.tech Food technology, I would suggest these video lectures for all the Branch of B.tech..appearing for GATE or other exams.. Lots of Respect to Sir🙏🙏🙏

One way to fix it without any effort would be to set your audio output to mono from studio. In case of mono audio output, the sound being played only on one side of the headphones would be played in both the sides. To do this in windows 10, go to ‘ease of access’ (just search for it) then to audio section and the enable mono. That should do the job.

Hi, any idea why the audio of this video is coming out of the right earphone only? Did you purposefully made it like that?
Nice explanation,easy to understand.
There are certain things which you cannot do
Always much better to do which we cannot do (rather than knowing everything we can do)
In short life doesn't matter
There are number of things which we can do heat engine can never be done just making tail of a horse straight
We know it cannot be made to occur under these circumstances
All branches there's a system
As last behaviors are all applied to the system
1 control mass
2 Control Volume
Control mass is system where it remains fixed- mass is controlled
There should not be any mapping direction
System boundary doesn't allow any mass interaction
Make quantity system same
No mass transfer
(across energy boundary)
Maybe energy interaction
So that mass control volume remains the same
Steady state control mass in mass out
Energy in energy out the same
Rule properties of volume must remain the same
Takeaway Properties of Control Volume must remain the same
Almost similar to control mass system
Difference is: the identity has changed
Control mass system allows control mass transfer to take place across the boundary
Across 2 main categories of system called isolated system
Tell if system is closed with no energy interaction
No mass interaction
No energy interaction
Closed system has already no mass interaction
Q. Why better define closed system
Define with a control volume with no mass interaction
So it's etter to define closed system
As mass interaction is restricted
along with it there is no energy interaction.
2 ways system interacts
1 mass transfer: m
2. Energy transfer: go in & out E
If both m = E= 0 then both are isolated
System properties remains in variant in time
As system not at all specific (to all surroundings)
Whatever is there containing in the system remains in variant in time
The system not specific (not at all)
Had got no link with it surroundings
Known as closed system
Thermo properties
Its characteristic features of system(can be specified) is identifiable, observable
E. G. How to specify certain features temperature volume
Any feature specified is the (innate property
How system is specified state of a system
Characteristic features, which system is specified
Mass pressure temperature
Volume
Has properties divided into 2 groups
1 Extensive property
Depends on the mass
Equals Zero when system is particle
2 Intensive
Properties which do not depend on the Extend of system
Internal energy enthalpy Entropy
When system contracts to point the has a finite value stress : pressure temperature
Intensive quantities
External energy per unit mass
Enthalpy per unit mass
Entropy per unit mass
If specified energy is defined at a point
Init start with these properties
Afterwards see there are large number of properties cannot be sensed! Or directly measured
Not because it's abstract
Defining state of the system is a requirement
Only when properties are uniform weekend can define a system (or it's hard)
First specify property that fix the state state
So that all property value should Have uniform Distribution
At any time there is continuous change of time
At least for a moment it has to be in variant in time at a state (of a system) at a static state define by properties
Takeaway
Every point function has a property as
State is represented by a point (coordinate diagram)
Why properties are told as State variables(point Functions)
Pertinent question
Minimum number of independent properties ( needed to fix that state)
N number properties should be some idependent Parameters m vars
Other m-n are automatically fixed
By certain equation
-(Number of independent intensive properties)
The property relation
F = c - phi +2
F n independent intensive properties
N of components
Phi number of phased (things)
Example c=1, d=1 (single phase(gas liquid)
F=2
C=2
Water vapor (ice)

thanks
There is an issue with the audio of Basic Thermodynamics please can the NPTEL team resolve this ??
Helpful to understand the concept
