    This professor just simplified and made me understand everything my professor is teaching me for the past 2 months of thermo class. His global story in the beginning was actually to help students understand the difference between macro and microscopic properties of thermodynamics. If you follow exactly what he is saying, it should make sense since he actually defines everything-which ALMOST every thermo professor will not do. Count yourselves blessed MIT students. And thank you for sharing!

    By breaking even he means energy is conserved in an isolated system. If you have 50 J of potential energy (U), that 50 J's of U can be converted into kinetic energy; problem is some energy will be lost due to friction. The energy that you do lose is forever lost to the universe. Hence, if you can reach absolute zero temperature (0K), you prevent the loss of energy due to friction. This is what he means by the 3rd law (you can never break even). Absolute zero can never be achieved.

    There is a lot of blather below regarding whether the lecturer, who is excellent, made a slight mis-statement of this point or that point. All of which is beside the point. What I learned from 5 years of work towards a PhD in physical chemistry is that once through the material is never enough. It takes a combination of live lectures, several textbooks, study guides, writing out mathematical derivations until you understand them, and endless problem solving.

    The Sun heats the Tropical waters, Deep Space super cools the Polar waters, hot water rises,cold water falls the result is the Ocean Conveyer that uses the difference between hot water and cold water to create Kinetic motion(repeat)
    As heat from the Ocean rises it created moist thermals, hot air rises, cold air falls and the difference makes wind by kenetics, as heat disapates it makes Clouds that rain(repeat)

    @Tanjiskas it means that you convert 100% of the heat you are inducing into the system into useful work. which means that the efficiency is 100%. actually the first never said that but it just didn't mind it. so the second law said that you cannot reach 100% efficiency because you are always generating entropy along the way and by increase in entropy you are wasting energy

    He means that the 2nd law defines the direction of spontaneous change. A process is spontaneous only if the total entropy of the system in which it occurs increases. For example, sugar dissolving in hot coffee occurs spontaneously -- sugar will only crystallize from hot coffee if energy is expended. i.e. the entropy of the universe must always increase--it follows the direction of natural change, a.k.a. the "arrow of time". The 2nd law is also about the reversibility of change No more room!

    pinned neutron superfluid provides an angular momentum reservoir as its rotation rate is determined by the areal vortex density, which is constant as long as it is pinned to the crust. At the same time, the crust continuously slows down due to loss of its angular momentum in the particle wind and electromagnetic radiation. At a critical lag in this differentially rotating two- component system, superfluid vortices get unpinned, dumping a large amount of angular momentum to the crust, which is observed as a spin-up in the crustal rotation rate, usually inferred by timing the radio pulse (Alpar et al. 1984a, 1985). This implies that the fractional spin-up provides a probe of the extent of angular momentum transfer and hence the MoI of the crustal pinned superfluid. The ratio of the MoI of the crustal pinned superfluid to that of the rest of the star, referred to as the fractional moment of inertia (FMI), can be related to the observed fractional spin-up

    Equal volume ratio liquids do not imply equal molar ratio. (In case you have not learned, liquids are pretty damn far from ideal gasses; water is denser and has a lower molecular weight than ethanol, equal volume ratio means much higher molar ratio of water to ethanol)

  • @RalphDratman
    @RalphDratman 5 ปีที่แล้ว

    You might notice that the common word "heat" is used as though we already know what it means. The lecturer does not define it. But if you look up "heat" in Wikipedia you might be surprised, as I was, to find that the definition is not obvious:
    "In thermodynamics, heat is energy in transfer [...] by mechanisms other than thermodynamic work or transfer of matter."
    Note the word "energy." Reading further in that same Wikipedia article:
    "As a form of energy, heat has the unit joule (J) [...] The standard unit for the rate of heat transferred is the watt (W), defined as one joule per second."
    So, according to the content of the lecture plus the content of Wikipedia, energy moves from a hot body to a colder body. The rate (per second) of energy transfer can be measured in watts. The total energy transferred can be measured in joules, or (as we know from looking at our electricity bill) maybe even in watt hours.
    Heat is energy. I personally do not find that obvious.

Given sufficient time, the contents of even the most robustly insulated container will reach equilibrium with the surroundings.

    Something's bothering me now. At 15:13. Isn't a thermos of coffee an example of a closed system rather than an isolated system? Some thermal energy will be lost over time - it's not as if your coffee remains at the same temperature indefinitely lol Feel free to reply to this comment with any helpful insights.

    Honestly I think the implications of not doing something about climate change is far more serious. Hurricanes like Katrina and Sandy have already caused billions in damage, and are only set to become more frequent. Add to that the billions in health care from air pollution, the cost of destroyed tourism revenue (reefs, forests, etc), increased drought/flooding, which affects crop yields & cause food prices to increase, the increase in fuel prices, people might be okay with a bit less luxury.

    Thermal is related to photons therefore our focus should be on photons. Changes in the saturation of dynamic photons within a system would lead to changes in temperatures either due to the presence of a heat source or heat absorber. Precisely temperature should be defined as the availability of dynamic photons per volume per time within a system.If there is a heat source, it would be flooded the system with abundant of dynamic photons and the effect would be to raise the temperatures within a system. On the other hand, if there is a heat absorber where heat (dynamic photons) would be sucked away would cause drop in temperatures. Atoms are constantly exchanging photons with the surroundings in which both nucleus and stationary electrons of an atom would stockpile dynamic photons from the surroundings before transforming them to stationary photons in which at the same time some stationary photons from the nucleus and stationary electrons of an atom would be released as dynamic photons to the surroundings. If the atom only gained more and more stationary photons than the ones that it dissipating to the surroundings due to high availability of dynamic photons within the system, the atom would increase its kinetic energy per time in which it would increase its vibration rates, or increase its transverse velocities, or both. Therefore changes in temperatures would lead to changes to the kinetic energy of atoms within a system.Total energy of a "system" (the entire universe) would always be the same. It is wrong to say the energy tends to move from high energy to low energy while entropy, S, moves from order to disorder. The total energy of the entire universe is always be the same. The universe is always there as per the law of conservation of matter. Einstein's famous equation, E=mc^2 is wrong otherwise garbage also can be used to make atomic bombs as long as it is matter or it has mass. We know this is not true. Energy and matter cannot interchange one another according to Einstein's famous equation. One must have photons before one can emit out photons. Photons are particles and they have mass. Dynamic photons possess momentum.The universe would expand to its maximum size before implosion and the final stage of implosion would be Big Bang where all celestial bodies would be flung outwardly to facilitate for expansion. NASA claimed that we can see the formative state of the young universe which clearly attests that all celestial bodies were travelling much faster than the speed of light in the past but somehow they have slowed down for quite sometime already slow enough now to allow the light of the past to catch up with us now to allow us to see the young universe. Imagine the celestial bodies would accelerate towards the center of the universe for billions of years where their speeds should be several times faster than the speed of light before they reaching the center of the universe; therefore the impacts of Big Bang is beyond our imagination. When celestial bodies been flung out from the center of the universe, their speed would also be several times faster than the speed of light. Therefore it is wrong to say that entropy moves from order to disorder. Thermodynamic should be the studies of photons. In God I trust.

The main reason is the capitalists comes out with ever increasing new products to get the consumer trained population and they get hooked to those products which consume fossil fuels. And this trend keeps growing because capitalist wants increasing returns and growth in his business. He wants ever increasing g demand which comes from ever increasing human population. . So who is to be blamed for global warming?

    "K" used to be called "degrees Kelvin." With the adoption of SI, they dropped the "degrees" part, so you simply say, or write "K," not "degrees K." But they are still degrees--of the same "size" as C degrees, but starting out at absolute zero.

    @sephirothsoul999 There is no 'true' isolated system unless you define the universe as a whole as your system. Instead you must decide if the energy loss to surroundings is significant.
    If your goal was to understand the heat lost from the coffee to the surroundings outside the thermos, then it wouldn't make sense to call the thermos isolated.
    If you wanted to understand something going on inside the thermos, say the coffee is melting ice, then the heat lost through thermos might be irrelevant
