10:45 The reaction of hydrogen (H2) and oxygen (O2) to form water (H2O) is a chemical reaction that releases energy therefore In this case, entropy tends to *decrease* because heat is taken away from the system

[@satyajeetdas1535]

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.

sir i have a question in 38:42 there is 1 mole of h2o is liquid in reactant side and 1 mole of h2o is gas in product side then how delta N=?-1 instead of 0

In 2nd case entropy should decrease coz entropy is inversely proportional to temperature. so if temp increases entropy should decrease.

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

[@vwvlogs3997]

bro agar pta chale to mujhe bhi bta dena ki aisa kyu hua kyuki jyadatar log increase comment kar rhe h

[@krishnakaushik2117]

as the temperature increases the particles start to move here there because there stability became low that's why the entropy is increases
