Thank you, Sir. It would have been impossible for me to understand this concept and thermodynamics on the whole if it hadn't been for your lectures. Thanks a lot, Sir.

hello sir, in dis video u mentioned dat if we join wire with bulb from its one end and othr to earth...earth se join krne ka kya matlab h sir..earth k undur kse daal dete hai (respect) plz ans ??

[@faizu.shaikh5776]

+deepika harjai simply hum bulb k positive ya negative wire ko earth se touch kr den ge to current earth me flow ho gae ga iss lie gab hum wire ko apni body se touch karen ge to hame current feel hoga kiun k current hamari body se flow hota hua earth me gae ga.

[@vibodhj349]

Dekho, earthing isliye kiye jati hai uska karan ye hai ki Potential difference jo hai wo earth aur us machine/appliance me appliance ke positive negative potential difference se kam hota hai. Iska fayda ye hai ki hame jhatka (shock) kam lagega.

[@upscaspirant8795]

Sir u r doing god's work...thank u

[@debayanpaul8928]

sir i have a confusion in previous video that 1. work done on gas -RAISES POTENTIAL ENERGY AND KINETIC ENERGY OF THE SYSTEM DUE TO WHICH TEMPERATURE RISES AND THERE MAY BE A CHANGE OF STATE .2.WORK DONE BY SYSTEM - HELPS IN PV WORK.3.IF PRESSURE OF THE GAS IS CHANGED (SUPPOSE BY GIVING HEAT TO IT BUT ITS VOLUME IS KEPT CONSTANT)- THEN HEAT ENERGY OF THE SYSTEM WILL CHANGE. IS MY ALL THIS CONCEPTS OK? PLPLPLPLPL REPLY. I AM WAITING FOR YOUR REPLY

[@prateekdang2407]

Sir on going from source to sink the specific heat do not change even on changing temperature.Why?

[@kanwalansari8158]

sir can we say compression of diesel engine is more than petrol engine thats why it is more efficient.

in indicator diagram u say that if temp is change in a process it must be adibatic.,sir why only adibatic it may be isochoric or isobaric

[@diplomat3565]

we take Q2 = msT2 but temp of gas T coming from system is hotter than temp of atomospheric gases ??? Sir please tell me

[@ranjantripathy5932]

sir how density is intensive quantity , if volume change then density will also change,so when we divide a substance externally as its volume is changing ,density must change

[@bejoyghosh6336]

+Prakash Chandra Tripathy Brother...density= Mass/volume .. and mass and volume they both are extensive quantity ...and it's a proven statement that when you divide two extensive quantities with each other the result is intensive...hope that helps

[@vibodhj349]

That is a pretty interesting thing. Thank you.

[@lolnllvln]

Prakash Chandra Tripathy if you change mass of a system then its volume also changes making the ratio constant

[@kanthrohithrajni4]

Sir you told abouy consistency.. i.e if lhs is extensive then rhs also has to be extensive...nd vise versa..but for density=mass/volume..density is intensive while mass nd volume r extensive.how is that so..?

[@avasarkarmandal]

Dear...dts applicable only for THERMODYNAMICAL EQUATIONS.....density=m/v isn't such an equation.... get clear concept babes!!!!!😆😆😆😆😆

Sir Thank you very much. You are an Excellent Teacher. I would like to request you to upload the lectures of biology also as soon as possible because I'm unable to understand many concepts. Kindly solve my problem by uploading the biology lectures too. Once Again thank you very much for doing such a wonderful job for students who are unable to understand various concepts of Physics.......:):)

[@prabalsaxena]

Respected sir, I have a confusion..u said , internal energy is extensive property but we know change in internal energy is related to change in temperature..so if temperature is intensive then how can b internal energy extensive...? Hoping for the reply

[@ankitaverma475]

NOTE:"An extensive property may become intensive by specifying unit amount of substance concerned." Moreover, for ideal gas , internal energy is function of tempture ( u r right). .......So,NOTE: " during isothermal process inc. Ideal gases, as temp is constant so internal energy will also become constant" in this case.....

[@prabalsaxena]

Yeah I got it.. Ty mam 😊

[@reetchoudhary96]

nice sir 🙏🙏🙏

[@Jashanrangpuri]

sir, we know that if temp increases then volume increases . thus expansion (increase in volume) leads to increase in temp . but in video u said the opposite

[@vibodhj349]

If you increase the volume of a system, its temperature will decrease because the gas in the system has to do work in order to expand so where will this work come from, it will come from the internal energy/kinetic energy of the gas molecules of the system. And internal energy has direct relation to temperature, okay? So temperature decreases when volume increases of the system. Kuch doubt hoga to puccho, fhir se samjayenge.
