thermodynamics क्या है? आसान हिंदी में समझाइए
Physics में thermodynamics का अर्थ है: the study of heat, work and internal energy in physical systems. यही बात हिंदी में, लाइव विज़ुअल के साथ समझने पर टॉपिक बहुत आसान लगने लगता है।
How to approach it step by step
LetMeTeach इस टॉपिक को स्क्रीन पर लाइव बनाकर, बोलकर हिंदी में समझाता है। आप बीच में रोककर दोबारा पूछ सकते हैं, आसान शब्दों में समझ सकते हैं, या भाषा बदल सकते हैं। यह एक-से-एक (1:1) रियल-टाइम टीचिंग है, इसलिए हर स्टेप आपकी समझ के हिसाब से बदलता है।
Worked example
तरीका यह है: identify the process, apply the first law ΔU = Q − W, then check entropy for feasibility. उदाहरण — In an isothermal expansion the internal energy stays constant, so all heat becomes work.
The mistake most learners make
ध्यान रखें: Confusing heat with temperature, which measure different quantities.
