The website, aimed at nurturing grasping power students, has classroom lectures on almost all the topics. It is an outcome of 23-year long toil of Physics expert who has made it a mission to simplify the complexities of Physics.

Ashish Arora, the brain behind this interactive unique website, has all his lectures available on web for free of cost. He has created a youtube channel in the name of Physics Galaxy. Today more than 6000 video lectures are being watched per day on this website which is highest among any other e-learning website in India. Till now more than 3.6 Million videos are watched on it. On each video subtitles are also available in 67 languages using google translator including English, Hindi, Chinese, French, Marathi, Bangla, Urdu and other regional and international languages.

Sir please explain why we didn't consider water being heated to 100 from 50 ? we are given to find the heat to "vaporize " ..vaporize means to boil right?

Amazing question (the vaporisation part got me)

according to my understanding complete situation is not given in question..temp of 1-x part has to be raised from 50 to 100degree celcius but heat for that will be provided by some other process happening in the situation

Sir i think there must be some conditions missing in this question because according to the logic that water will directly evaporate we can say that very cold water say 2°C will directly evaporate without further rise in temperature during heating. Please explain sir🙏🙏

Sir this isn't seems to be practical as the ice will form gradually and the temperature of water will raise.. If this was a sudden process then it could happen..

Kelvin is not considered
Because specific heat in in K

Bhai log ek baat Jaan lo. Physics ka problem solve karne se pahle problem ka analysis karna sikho ki problem me ho kya raha hai aur jo puchha ja raha hai wahi q puchha ja raha hai. Ye koi nai bataayega aapko. Ye aapko khud hi karna hoga. Sirf problem ka solution dekhne se aaplogo ko physics kabhi nai ayega.
