Always a fan of NPTEL. thanks to you people and Prof. B.S. Murty. If we can have an Index in between individual lectures to jump directly to that portion of the video. lets say in this this video I only wand the concept of Phases so you can direct me to 21:00 tor this mentioned sub topic. Thanks for the knowledge.
sir grain boundaries and other impurities have high free surface energy so according to the delta G equation at 47:43 we need more undercooling and more delta Gv for the delta G to be 0 or negative na? so how come there is no undercooling or less undercooling required in heterogenous nucleation?
sir, i have some confusion,u told that in G vs T curve,at T=0, G will have an intercept H as G- H- TS but at T=0 ,H will also be zero as H = integral of Cp dT. could you please clear my doubt.

I completed this course during my post graduation at IITM-2006-08, still whenever I am feeling low I watch Prof BS Murthy's teaching
excellent lecture... You have a natural ability as a professor to teach. Thank you.

wonderful lecture given by a knowledgeable and enthusiastic professor! Thank you!
one of the best lecture I have ever listen on NPTEL
Great lecture. I enjoy listening to professor Murty
I highly enjoy your teaching - Thanks a lot for your effort in Materials Engineering!
Probably one of the best lecture I've seen on nptel
EXCELLENT LECTURE WITH GOOD INTERACTION !!
NPTEL Online Certification available in this course! Study, write an exam and get a certificate from the IITs! Check nptel.ac.in/noc
thank you Prof.....keep on helping us ..good work,!
it is really very interesting to learn in this way.
Extraordinary lecture............🙏🙏🙏
Amazing lecture sir !
AWSOME LECTURE SIR
Very nice lecture, thank you.
Thank you proff. .......brilliant lecture.
Very Nice concepts cleared
great lecture sir. hats off
sir suppose we take ice(at 0 degree celcius) and put it in liquid all at 0 degree will ice starts to melt ?? temp maintained at 0 degree centigrade
Solid ice will act as nucleating site and everything will freeze.

Sir you have considered constant pressure in calculating Maxwell's equation then why does dp is not zero when dh is Tds
good lecture.......sir
nice........
Mind blown!
So clear 🔥🔥🔥🔥🔥
great lecture!

Blown 🤯
G= H - TS
