first work on your writing dude

Nice presentation. I first came across the Legendre transform in Thermodynamics without an explicit reference to what it entailed. "A graphical derivation of the Legendre Transform" by Sam Kennerly (12 April 2011) and "Making sense of the Legendre transform" by Zia, Redish & McKay, American Journal of Physics, vol. 77, (7), July 2009 present enlightening discussions on the Legendre Transform.

Hi. Great video, thx. Comparing the two equations (starting at about 4:16) for M_tot, one would, like you mention, think V'_A could be MW__A/rho_soln. You mention that this would give V'_A as a function of density, (and hence imply, I'm guessing, not useful for further calculations...) but don't go into this further, or discuss whether or not MW_A/rho_soln is equal to V'_A. I've used this procedure for calculating partial volumes of a binary soln. given density data, and this worked well. Also, the first eqn. for M_tot using MW_A and MW_B gives an understandable result, however MW_A/rho_soln is still not equal to V'_A as calculated with this method here (which uses the other eqn for M_tot), so I'm very confused about this detail. Why isn't MW_A/rho_soln equal to V'_A?

Clearest thermo explanation of Legendre on YT

Thanks a lot!

Would it not be easier to omit the d and instead put delta

Thank you!

What happens in case of compression where pdv is positive ? It wouldn't cancel

HOW AND WHY THE CANDLE FLAME IS ROUND AND BLUE AT “ZERO" GRAVITY IS ALSO CLEARLY EXPLAINED BY WHAT IS E=MC2 (ON BALANCE): The candle flame is round and blue at “zero" gravity for the same reason that WHAT IS THE EARTH is blue ON BALANCE. In “zero" gravity, the flame is cooler, spherical, blue, and centered on the candle wick. There is a PALE blue flame as opposed to what are the familiar candle flames (BRIGHT yellow-white) ON WHAT IS THE EARTH, when this candle flame is TEARDROP in shape, basically yellow, and mostly well above the wick. ON BALANCE, consider the blue flame ON THE EARTH along WITH the colors of WHAT IS THE SUN in the sky. When “coolest”, lava is red (and it is blood red too); but lava is MAINLY ORANGE (ON BALANCE), AND it is even YELLOW (when it is at it's HOTTEST). Also, notice that water is an excellent conductor of ELECTRICITY. CLEARLY, GRAVITY (importantly, as it has been written) is an INTERACTION. Notice the orange AND setting Sun in DIRECT comparison to/WITH what is the fully illuminated, WHITE, AND setting Moon. (The Moon is ALSO BLUE). Excellent. Also, consider what is THE EYE (ON BALANCE). The sky is blue, AND THE EARTH is ALSO BLUE. The stars AND PLANETS are POINTS in the night sky. The tides are CLEARLY AND necessarily proven to be ELECTROMAGNETIC/gravitational (on/in what is BALANCE). FANTASTIC. It ALL CLEARLY makes perfect sense ON BALANCE, as BALANCE AND completeness go hand in hand. Beautiful. Green is the color of what is living ON BALANCE. Great. Think about what is fire, of course, ON BALANCE. Indeed, consider what is lightning ON BALANCE (as well) in relation to clouds AND what forms as water. Finally, ON BALANCE, consider that what is the Moon is comparatively “pale” in relation to what is THE EARTH/ground when they are seen from outer “space”. Accordingly, ON BALANCE, what is (CLEARLY) the BALANCED MIDDLE DISTANCE in/of SPACE is to be DIRECTLY compared WITH what is (and represents) E=mc2 (on/in BALANCE) !!! Beautiful. ON BALANCE, notice that the rotation of WHAT IS THE MOON matches it's revolution. Clearly, E=mc2 IS F=ma on balance, as ELECTROMAGNETISM/energy is (CLEARLY AND necessarily) proven to be gravity (ON/IN BALANCE) !!! Accordingly, gravity AND ELECTROMAGNETISM/energy are (CLEARLY) linked AND BALANCED opposites (ON/IN BALANCE). Indeed, consider the speed of light (c) ON BALANCE. E=mc2 is CLEARLY F=ma on/in BALANCE. Consider TIME (AND time dilation) on balance. This NECESSARILY represents, INVOLVES, AND DESCRIBES what is possible/potential AND actual (IN/ON BALANCE). Magnificent ❤️ !!! Consider what are red, orange, and yellow in comparison with what are blue, indigo, and violet. Think E=mc2 !!! Think MIDDLE DISTANCE in/of SPACE ON BALANCE !!!! GREAT !!!! Think GREEN !!!! Think about “natural” flames in relation to temperature ON BALANCE !! Excellent. By Frank DiMeglio

1. 2000 J of heat leaves the system and 2500 J of work is done on the system. What is the change in internal energy of the system? 2. A gas is compressed at a constant pressure of 0.800atm from 9.00 L to 2.00 L. In the process, 400 J of energy leaves the gas by heat. (a) What is the work done on the gas? (b) What is the change in its internal energy? 3. A system absorbs 35J of heat and in the process it does 11J of work. (a) If the initial internal energy is 205J what is the final internal energy? (b) The system follows a different thermodynamic path to the same final state and does 15J of work, what is the heat transferred? 4. A thermodynamic system undergoes a process in which its internal energy decreases by 500J. If at the same time 220J of work is done on the system. Fined the heat energy transferred into or from it. 5. What is the change in internal energy of a system if it absorbs 400KJ of heat from the surrounding and does 500KJ of work on the surrounding

How can partial molar volumes of components for quaternary solution be calculated?

nice

Im here because its my science project

What stands MW(A/B) for ? i didn't catch it ://

How come you're allowed to use the "dv" like that when integrating? Is that just a rule of integration. Anyway thanks for the video.

How to solve p2/p1=(T2/T1)^(n/n-1)

Well explained.....

ahg wish i saw this sooner

Thankyou sir🥰

finally

Thank you.

Good but please use some dark colour to write

Sorry i can't understand any word

Impossible to understand such good handwriting

Sir please improve your handwriting

Please maintain the handwriting .And I really like this video. Please upload more videos

"polyprotic"

thank you!

for better understanding and better learning do watch ua-cam.com/video/k0PPj_2DZn4/v-deo.html subscribe us and support us

this video is underrated

Nice discussed

thanks for this video, I was able to understand the concept easily

Nice sir get it very well

this is no good explanation, see Khan Academy's derivation, that's way more accurate

very polyprotic of you

Incredible video, very educational.

great video!

Thank you! Your diagram at the beginning was very helpful

Wow! That was fun and you even gave us a cool little applet to do all those calculations. Very nice. Now you can put each of the variables on a graph and see how they change. I wonder about the assumption, however, that the two liquids are the same as water. Each of the solids in the liquid has its own heat capacity, right? So that would change the overall heat capacity of the water plus the solids in it?

This is a very clear step by step explanation of how a polytrope is calculated from the ideal gas law and two interactive gases. The graphs are clear and show what happens to pressure and volume and temperature when you change the polytrope exponent "eta". I wish an example using astrophysical processes such as interacting interstellar gases or neutron star density and pressure had been given, but I will seek out other video's for that. Thanks for a clear derivation.

😂😂😂😂😂😂👎👎👎👎👎👎👎👎👎👎👎👎👎👎

Bruh you took it too long We know; PV=nRT and KE=1/2MV² Where V=√3RT/M THUS KE=(3/2)nRT

Clear and concise. Thanks!

Good video

Confusing

pretty sure you did this wrong but whatever
