However, places like Gaza and Cox Bazaar have around 4 children and such places can never become self sustaining.They will if half the kids die.
What makes you fail to distinguish between impedance and refractive index?The fairly close relationship between them.
I shall inform you that many motorhome and caravan heaters are diesil, not gas,That's a fairly pointless thing to tell someone who was talking about ..
I see a lot of people buying those cheap diesel heaters.The only difference seems to be that you didn't spell it correctly.
It is a good way of storing energyNot really.
but you need a vent.So what?
What "point" are you trying to make here?Unfortunately the makers of infrared heat lamps do not share your profound knowledge!A good absorber is also a good emitter in the same spectrum. That's where infrared heat lamp can optimize it.
But lower frequency radiation should also be considered.
Short video about the importance of grounding your heat lamp.
Most of us know that impedance is frequency dependent. Mathematical model for impedance is a complex number. Thermodynamics and black body radiation seem to consider only the real part of this impedance. That's because in those cases, the imaginary part is not significant. They're only special cases from the more general cases where the radiating or radiated bodies are not necessarily black body.You have that more or less exactly wrong.
It's understandable that scientific research started with simpler cases. But let's not forget that there are more than what earlier discovery has told us.
I've just realised that Lockets throat lozenges make a cough and sore throat worseWhat's the evidence base for that assertion?
In this scenario, we get an increase in system entropy without any change in temperature nor internal energy.Lucky us!
I think it's necessary, since you didn't seem to realize how insignificant it was.As I said,
you don't know what the phrase "in principle" means.
IMO, the biggest factor in determining P vs NP problem is because the problem isn't well structured/defined.And is your opinion well informed?
Personally I would consider aspartame to be preferable to some of the other sweeteners, saccharin, acesulfame and sucralose as these are synthetic substancesCyanide and arsenic are natural.
aspartame is a peptide ester.Botulinum toxin is a peptide and I doubt that sticking a methyl group on it would affect its properties much.
Here's another thought experiment to check our understanding of temperature, and its relationship with entropy.
Two isolated containers each with 1 cubic meter volume. Their internal surface is perfectly elastic, thus doesn't absorb energy from molecules hitting it. A small pipe equipped with a closed valve is connecting those containers. Initially, the first container contains helium gas at STP, while the second container is at vacuum. The whole system is inside a space lab, isolated from outside world.
When the valve is opened, some gas molecules will move to the second container. Since the collision with the container walls are elastic, they maintain their kinetic energy. At equilibrium, the flow rate from the first container equals the reverse flow. The pressure of both containers become half of standard pressure. The temperature is still at standard temperature, according to ideal gas law, P.V=n.R.T
The gas, which initially occupied 1 cubic meter of volume, now occupy 2 cubic meter.
Why do you keep posting stuff that we clearly already know?
That's a lot of trouble to go to in order to show that you don't know what the phrase "in principle" means.The experiment in the video clearly shows this.But, in principle, your spinning magnet warms it up a bit.The effects are much less than Eddy current generated in metals, thus doesn't significantly change the temperature measurement.

But we know that glass melts at its melting temperature.We know that the melting point of something (when it has one- glass doesn't) is defined as the temperature where the liquid and solid phases are in equilibrium.
If you look carefully, you will se the only bits of the line where the temperature is constant are the bits where there are two phases in equilibrium.And, if it's not at equilibrium, it doesn't have a properly defined temperature.If that's the case, the curve below won't be possible because the temperature is measured while heat is being transferred to/from the system.
It will melt before reaching equilibrium.I know.
And it would melt
According to Kirchhoff's law of thermal radiation, a good absorber is also a good emitter for the same radiation frequency.There's a good chance that I told you about Kirchhoff's radiation law. I have cited it quite a bit in these pages.
Note that objects heated by radiation from incandescent lamps can have higher temperature than the glass surface of the lamps. This pose question about thermal contact. Is exchange of kinetic energy through radiation counted as thermal contact?
I spent several years working on "dynamic equilibrium" calorimeters for measuring ionising radiation dose rates. Long story but it was a cunning way of measuring millidegree temperature changes to better than 0.1% precision.So... not Joule's method.
The classic Callendar and Barnes continuous flow water calorimeter uses a similar principle.
