    He passed away at January 14, 2020.
    He will live through the minds of millions of engineers in our country and this channel make him live through the minds of future students also.
    May his soul rest in piece 🙏🙏

    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

    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 .👍

    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.

    🎯 Key Takeaways for quick navigation:
    01:05 📖 *Thermodynamics originates from the Greek words "therme" meaning heat and "dynamic" meaning force.*
    02:33 🔍 *Natural processes occur with rhythm and directional constraints, exemplified by heat flow from high to low temperature.*
    04:52 🔄 *All natural processes abide by certain laws, like the conservation of energy, forming the basis of thermodynamics.*
    07:40 📊 *Thermodynamics describes laws governing physical processes, energy transfer, and relationships between properties.*
    09:08 📏 *Macroscopic and microscopic views in thermodynamics differ in focus: macroscopic emphasizes observable quantities, while microscopic delves into molecular behavior.*
    12:49 📚 *The course covers a range of topics, from basic definitions to laws and properties of substances, emphasizing practical applications.*
    19:44 🌐 *Thermodynamics plays a crucial role in energy efficiency, environmental sustainability, and understanding the limitations of physical processes.*
    22:14 🚫 *Thermodynamics helps identify what cannot be achieved, essential for efficient resource allocation and avoiding futile endeavors.*
    26:20 🧱 *A system is defined by a boundary that separates it from its surroundings.*
    27:11 📦 *In a control mass system, mass and identity remain fixed, while volume may change.*
    28:33 ⚖️ *A closed system restricts mass transfer but allows energy transfer.*
    29:21 🌀 *A control volume system is bounded by a control surface and may allow mass and energy transfer.*
    31:01 🔄 *In steady-state control volume systems, mass and energy entering and leaving remain constant.*
    33:22 📊 *Thermodynamic properties are identifiable characteristics of a system, specifying its state.*
    35:16 💼 *Extensive properties depend on mass, while intensive properties do not.*
    39:26 🔒 *To specify a thermodynamic state, properties must be uniform and invariant with time.*
    44:13 🔢 *The number of independent intensive properties to specify a system is given by the Gibbs phase rule.*
    48:19 🔄 *For a system to be in thermodynamic equilibrium, it should not interact with the surroundings, ensuring uniform properties.*
    52:01 🔍 *Thermodynamic studies consider intermediate states as equilibrium for simplicity, enabling specification of system state points.*
    53:52 🔄 *System A interacting with system B constitutes an isolated system, where each system acts as the surroundings of the other.*
    55:18 🌱 *In practice, thermodynamic equilibrium is approached through processes divided into infinitely small stages, termed quasi-equilibrium.*
    56:14 💨 *Absolute vacuum does not define a system in physics; systems are not defined in absolute vacuum conditions.*

    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.

    However in our india due to low speed ,such high quality video takes 6 hrs to play.
    kindly give option of low resolution just like other courses of nptel.

    Sir, u said that Gibbs phase rule gives the no. Of intensive properties but my question is how can we identify the property from those 'n' no. Of properties..?

    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)
