बोतल में ठंडे पानी का तापमान बाहर के तापमान से अलग होता है जिसके कारण से आसपास उपस्थित वाष्प द्रव के रूप में बदल जाती है

सर जब यह क्लास लाइव नहीं है तो फिर इसमें आप रिवीजन क्यों कराते हैं क्योंकि जिसको रिवीजन करना होगा तो पिछली क्लास को replay कर के देख लेगा |दूसरी बात जो चीज ना पता हुआ करे उसे आप गलत ना पढ़ाएं| आप बता रहे हैं कि पसीना निकलता है उड़ता है पंखा की हवा से सूख जाता है जबकि पंखा की हवा से उसका टेंपरेचर लो होकर वह तो और ही बूंदों में बन जाएगा| धरती पर 71% जल है फिर भी जल संकट आपके ऊर्जा संकट का उत्तर इसी जल संकट में है

good evening sir, 1-Due to Condensation small droplets made on outer surface of bottle . 2-As now-a-days we get more and more dependent on the energy because we developed a lot of electronic devices and many more things which are operable only through energy ,now all these things have been a part of our life thats why we feel an energy crisis , even if on a single day electricity get disturbed, as we know ENERGY CAN NEITHER BE CREATED NOR BE DESTROYED then also why we are facing energy crisis ? because resources are limited from which we make electricity (except clean energy sources, these can't fulfill a vast demand of energy alone). when energy changes from one form to another and finally get merges in environment and we don't know how to recover energy from environment and use it again.

Botal ke bahar pani ki bunde temperature ke difference ke karan aa jata hai..qki botal me thanda pani ke karan temperature low hota hai aur vayumandal ka temperature usse jyada hota hai ,jab High temperature low temperature ke sampark me aata hai to sanghanan ki kriya hone lgti hai jo hme bund ke rup me dikhai deti hai..
