The video covers the key concepts of thermodynamics, including entropy and Gibbs free energy. It explains the meaning of entropy as the degree of randomness or disorder in a system, and how it can be used to understand the spontaneity of processes. The video then introduces the concept of Gibbs free energy, which represents the portion of a system's energy that can be converted into useful work. It also discusses the relationship between Gibbs free energy, enthalpy, and entropy, and how these concepts can be used to predict the spontaneity and feasibility of chemical reactions. Key Points Introduction to Thermodynamics Part 2 [0:03] Welcome to the science channel where teachers teach from the heart and mind. [0:11] This is the last part of the thermodynamics chapter, so we will complete thermodynamics today. Entropy [2:31] Entropy is the degree of randomness or disorder of the particles in a system. [3:12] The more random the motion of the particles, the higher the entropy. [4:15] Gases generally have higher entropy than liquids, and solids have the lowest entropy. [4:39] The formula for change in entropy is related to the amount of heat added to the system divided by the absolute temperature. Gibbs Free Energy [6:45] Gibbs free energy represents the portion of a system's energy that can be converted into useful work. [7:48] The formula for Gibbs free energy is: ΔG = ΔH - TΔS, where ΔH is the change in enthalpy and ΔS is the change in entropy. [15:12] If the change in Gibbs free energy (ΔG) is negative, the process is spontaneous. If ΔG is positive, the process is non-spontaneous and requires an input of energy. Numerical Examples [22:32] The video goes through several numerical examples related to entropy and Gibbs free energy calculations. [33:50] One example involves calculating the enthalpy of formation of methane (CH4) using the given enthalpy values for the formation of CO2, graphite, and H2. [55:56] The final example asks to find the temperature at which a particular reaction becomes spontaneous, based on the given values of ΔH and ΔS.

The video covers the key concepts of thermodynamics, including entropy and Gibbs free energy. It explains the meaning of entropy as the degree of randomness or disorder in a system, and how it can be used to understand the spontaneity of processes. The video then introduces the concept of Gibbs free energy, which represents the portion of a system's energy that can be converted into useful work. It also discusses the relationship between Gibbs free energy, enthalpy, and entropy, and how these concepts can be used to predict the spontaneity and feasibility of chemical reactions.
Key Points
Introduction to Thermodynamics Part 2
[0:03] Welcome to the science channel where teachers teach from the heart and mind.
[0:11] This is the last part of the thermodynamics chapter, so we will complete thermodynamics today.
Entropy
[2:31] Entropy is the degree of randomness or disorder of the particles in a system.
[3:12] The more random the motion of the particles, the higher the entropy.
[4:15] Gases generally have higher entropy than liquids, and solids have the lowest entropy.
[4:39] The formula for change in entropy is related to the amount of heat added to the system divided by the absolute temperature.
Gibbs Free Energy
[6:45] Gibbs free energy represents the portion of a system's energy that can be converted into useful work.
[7:48] The formula for Gibbs free energy is: ΔG = ΔH - TΔS, where ΔH is the change in enthalpy and ΔS is the change in entropy.
[15:12] If the change in Gibbs free energy (ΔG) is negative, the process is spontaneous. If ΔG is positive, the process is non-spontaneous and requires an input of energy.
Numerical Examples
[22:32] The video goes through several numerical examples related to entropy and Gibbs free energy calculations.
[33:50] One example involves calculating the enthalpy of formation of methane (CH4) using the given enthalpy values for the formation of CO2, graphite, and H2.
[55:56] The final example asks to find the temperature at which a particular reaction becomes spontaneous, based on the given values of ΔH and ΔS.

Bhai kitne saare topics uncovered h zeroth law fazan ruke kuch ni karaya free expansion wgera kuch nhi

Bhai dusre me increase kaise hogi bata sakte ho?
@@sood.kshitijbro jb crystalline solid ka temperature increase krenge toh wo liquid or vapor me converr hona start hoga or liquid ki entropy solid se zyada hoti h or vapor ki liquid se bhi zyada hoti h. Toh entropy bd rhi h na.
@@helloeveryone6614Bhai agar formule ke hisab se dekhe to S = heat/ temp he
To S is inversely propotional to temp
Hence temp bhadega to S decrease hona chaye na?

Thank you sir ❤
Hlo
Bhai yhn se mat padh bohut saare concepts nahi padaye
13:50
In the following:-
(i) S decreases
∆S=-ve
(i) S increases
∆S=+ve
(iii) S increases

Tomorrow is my chemistry exam and thi vdo really help me♥️♥️
Itne sare topics toh nhi karae bhai.....🫡
11:22 1) Entropy decrease, 2) S increase 3) S increase.

i)entropy decreases
ii)entropy increases
iii)entropy remains constant
can you explain me why the entropy will increase if s=heat/temp means Entropy is inversely proportional to temp?

And thnq so much sir for completing thermodynamics in only 2 lectures plz start equilibrium after this.

Sir you are the best 🙏 thank you itna ache se padhane ke liye
11:30 ist = entropy decrease
2nd= entropy increase

delta s jab h /t hai tab temp badhne par delta s ghatna na chaiye ?? 2nd case mein

1) decreases
2) increase
3) "
38:48. Answer is 998.87 Joule per mol 😊
is it correct
Its wrong because sir made a mistake in conversion from kilo joule to joule in joule it should be 41000
Best example pf ENTROPY.....
Jb striket teacher class me hote hai to ENTROPY Lag bhag 0 hoti hai....Or jb vo teacher class se bhar jaaye to ENTROPY bhaut badh jaaegi 🙏❤️❤️.....

In 2nd case entropy should decrease coz entropy is inversely proportional to temperature. so if temp increases entropy should decrease.
@@nishthakumar1045 no it will increase because their is an increment in temperature due to which heat is increasing and the particles will have more space to move.

Great explanation of thermodynamics! The examples made understanding entropy much easier. Thanks for breaking it down so clearly.
13:02 sir but entropy ka formula to Heat/T hota hai na? So if T is increasing then entropy should decrease mathematically right?
Yes but because temperature increase therefore heat also increase because of temperature difference from 0 to 115 k
@@MaanSaab-dh3dneven if what you said was correct , temp would increase with the heat so, it would make it to be constant

So earlier formula for entropy was given as S= Heat/Temperature but then in the explanation of (ii) at 12:50 where the temperature INCREASES, entropy is also INCREASING. How? Someone please explain this
bro agar pta chale to mujhe bhi bta dena ki aisa kyu hua kyuki jyadatar log increase comment kar rhe h
as the temperature increases the particles start to move here there because there stability became low that's why the entropy is increases
