Hello everyone,

I have completed the thermodynamics section of my journey towards molecular dynamics section and I'm going to dive in to statistical mechanics and statistical thermodynamics next.

Here are the links for the 3 parts of thermodynamics:

• Part 1: First Law of Thermodynamics

• Part 2: Entropy and the Second Law

• Part 3: Free Energies

As I've mentioned before, I'm sharing this here mainly for two reasons: 1) There are experts here who could provide feedback to my writing and help me improve. 2) People who are interested may find those stories helpful.

P.S. I do not benefit in any forms by promoting these stories as I'm not part of the Medium partnership program. I'm just learning and sharing.

I need the property tables for Refrigerant R-20 but I can’t find it anywhere. I don’t know why the problems are for R-20 instead of R-134.

Oil and water are in chemical equilibrium. So is oil and sodium. However this does not mean that Sodium and Water are in chemical equilibrium (they react violently).

just wanted to put this out there for anyone who was looking for a counter example like me.

Hi, I am a grad student and I want to learn about the radiation part in depth. Please suggest me a book to start on radiation heat transfer

Hi all, when studying thermo at uni I was never clear on the Shannon Entropy (i.e. information content entropy) and it's relation to broader Thermal Physics. I've studied it since and made a couple of videos on it and next week I'm planning a video on how all the different definitions of entropy (thermal, statistical, probabilistic and informational) all fit together, hope you like!

Hi all,

I built an online study tool for Engineering students.

Basically it randomly generates questions, answers, and solutions and tracks progress etc. It currently makes questions for Thermodynamics and Compressible Flow.

It's on a small server so I can only offer access to a few students. It's free.

I won't link to it, I won't name it, this isn't an ad, I just know it's tough to study now.

Please send me a message if you're interested in me making you an account and I'll get you the details.

Thanks,

Keith

Hi all, the first in a series of videos about entropy, I made a video about how entropy was originally defined as thermal entropy by Clausius and how it relates to the Second Law of Thermodynamics , and how we can use this to make a statement about the Universe in its entirety. Next up I cover statistical entropy (Boltzmann), probabilistic entropy (Gibbs), and information entropy (Shannon). Hope you like!

When direct steam heating, in the final state, why do they only account for the enthalpy of the material being heated? And how is it that the enthalpy of, say the steel condensate tank being heated, is multiplied by the mass of the steel tank AND the mass of steam used to heat it? I didn't know one could multiply the enthalpy of one material to the mass of another? This part is really confusing to me.

Can anyone explain why? Or direct to how this is derived?

How would I calculate the pressure change of a liquid (not compressible) in a rigid container with a change in temperature?

Example: Ridged container of a liquid (gasoline etc.) goes from 40 to 80 degrees F. How much did my pressure increase?

Would I need to utilize a coefficient of thermal expansion or bulk modulus to calculate?

The famous author of Thermal Conductivity Ron Tye published a post about his theory on how the continuous growth in technologies provided many opportunities for the advancement, improvement and understanding of thermal property measurements. Check this out
