Properties of Pure Substances - Thermodynamics

Hello Everyone!

This video is the third one in a series of videos discussing the engineering thermodynamics. Here, I will discuss the definition of a pure substance, talk about different phases of a substance and phase change, show the phase change on property diagrams, teach how to use/read property tables, and finally introduce the ideal gas equation as arguably the most famous equation of state.

Make sure to also check the recitation video for this topic here:

Wow I am short of words I can’t believe this is so simple to understand thank you so much please continue other topics like compressible flow and heat transfer

[Raniaska]

Man you just explained the entire chapter in 60 minutes which took my prof at least 3 hours to teach x)))) Thank you so much!!

[dimitriladas]

this is probably the best lecture ive seen online

[adriandesixto]

this is helpful for us students suffering from
online class, thanks a lot

[abeerhussain]

Thank you so much Sir!! only in one day I understood Pure Substances.. You are the best :)

THANKS, A LOT, FROM YOUR VIDEO I EASY to LEARN ABOUT THIS CHAPTER

[frankafroson]

this teaching is understand everything, thanks a lot.

Prof you are truly a live saver. love your examples & analogies which helps me understand & remember the concepts. Pressure Cooker ❤ 👌👌Thank you so much for this great video.

[semalseniru]

thank you very much, this will help me pass my exams

[rkb]

Thank you sir for this very helpful tutorial..

[vishalsathiaseelan]

its Great Coincidence 😊 that Prof is using the same Reference Book as me Thermodynamics An Engineering Approach. Cengal CA, M A Boles

[dasundimantha]

Thank-you very much, sir ❤❤ This is very helpful for me.

[leulabera]

I loved the video. you are an amazing teacher. I am hopefully expecting other mechanical engineering courses also.🙂

[sivaramraj]

Thank you so much for the class buddy 😭💥

[quadripopoola]

Thanks you are the best. I loved everything about the videos

[mohmadsaber]

I guess thermodynamics is easier now ! :)

[pfischer]

Are you going to do a refrigerant cycle video please :)

[imdivyaaaaa]

it is really helpful. thank you and do more about on execises and solving problems.

excellent video. Thanks. I have few doubts. I am just a beginner so my question could be silly. At 15:5 you said the latent heat is a function of ( P, T). I didn't get this point. Following your video, I understand it is dependent on the pressure alone. At 39:58 you said 2 intensive and independent properties. I know about intensive, but not sure what is intensive and independent mean.
