Good afternoon sir ji Kya hi to mehnat karte aap hamare liye pure ek hi institute se akele lad Rahe aap sirf akele Na Koi aapke piche Na Koi aapke aage dusre institute per Puri team rahti hai lekin aapko aapke upar bahut khus hona chahiye Apko dekh kr hi me gate ke liye mehnat krta hu I am very proud to you sir ki main aapse padhta hun thank u so Much sir❤❤❤❤❤
Ans od question at 7hr 5mint is Enthalpy Change in Both Processes: Since the temperature change in both processes is the same (from 40°C to 80°C), the enthalpy change will be the same in both processes. Thus, options A and B are incorrect, because enthalpy change depends only on the temperature difference and mass of water, which are identical in both cases. Reversibility: Process-I involves a large temperature difference (water is heated from 40°C directly by a source at 80°C). This large temperature difference implies more irreversibility due to greater entropy generation. Process-II uses two heat sources, reducing the temperature difference during heating in each stage. Therefore, Process-II is closer to reversibility, because smaller temperature differences lead to less entropy generation and more reversible behavior. Thus, option D is correct.

Good afternoon sir ji
Kya hi to mehnat karte aap hamare liye pure ek hi institute se akele lad Rahe aap sirf akele Na Koi aapke piche Na Koi aapke aage dusre institute per Puri team rahti hai lekin aapko aapke upar bahut khus hona chahiye
Apko dekh kr hi me gate ke liye mehnat krta hu
