Reasons Why Reading Books Should Be Part of Your Life:
1. Knowledge Highway: Books offer a vast reservoir of knowledge on virtually any topic imaginable. Dive deep into history, science, philosophy, or explore new hobbies and interests.
2. Enhanced Vocabulary: Regular reading exposes you to a wider range of vocabulary, improving your communication skills and comprehension.
3. Memory Boost: Studies suggest that reading can help sharpen your memory and cognitive function, keeping your mind active and engaged.
4. Stress Reduction: Curling up with a good book can be a form of mental escape, offering a temporary reprieve from daily anxieties and a chance to unwind.
5. Improved Focus and Concentration: In today's fast-paced world filled with distractions, reading strengthens your ability to focus and concentrate for extended periods.
6. Empathy and Perspective: Stepping into the shoes of fictional characters allows you to develop empathy and gain a deeper understanding of different perspectives.
7. Enhanced Creativity: Reading exposes you to new ideas and thought processes, potentially sparking your own creativity and problem-solving skills.
8. Stronger Writing Skills: Immersing yourself in well-written prose can improve your writing style, sentence structure, and overall communication clarity.
9. Improved Sleep Quality: Swap screen time for a book before bed. The calming nature of reading can help you relax and unwind, promoting better sleep quality.

Abstract:
Dynamic, non-isothermal analysis of the pyrotechnic mixture of a sound-producing fire cracker, KNO3/Al/S/H3BO3, was carried out under N2 atmosphere by using a simultaneous thermogravimetric and differential thermal analyser. Intermediates and the residue formed in each stage of thermal decomposition of the pyrotechnic mixture were characterised by X-ray diffraction analysis and the most probable reaction pathway was proposed. Thermogravimetric (TG) and differential thermogravimetric data (DTA) were used for the interpretation of the mechanisms and kinetics of decomposition by means of a model-fitting method, the Coats–Redfern equation, and model-free methods, the Arrhenius and Kissinger methods. The values of activation energy (E) were calculated as 11–16 kJ mol−1, 24–53 kJ mol−1 and 15–56 kJ mol−1 for stages I, II and III respectively by the model-fitting method, with the Avrami–Erofe’ev model (A2), two-dimensional model, nucleation and growth mechanism. The pre-exponential factor (ln A) of each stage of thermal decomposition at various linear heating rates was calculated and the probable decomposition mechanism was proposed for the first decomposition step as the expulsion of sulphur, and the second and third decomposition steps as the conversion of aluminium to alumina are obtained. Similarly, the reaction was also found to be first order.
