Other posts are addressing your main question, but I want to take a sec to correct your conclusion about germs.

The germs are not being dissolved in hot water. Bacteria will not break apart in any water that would be safe to touch. The soap helps to break down fats and oils on your skin so they can be rinsed off easier, and the scrubbing action of your hands does the work of actually getting things off. You can just as safely wash with cold water, but most people find warm to slightly hot water more comfortable.

Not just that.

He is talking about running size.

Add temporary folders, ram image file for sleep mode and the like.

Is question can be replaced with people:

"how is it that a baby is so small but it requires a lot of room when it wants to run as ann adult" .

The answer to both questions is "they are unrelated".

ELI5: Almost everything is more soluble in hot water than cold water. Including Soaps. The soap is what cleans the germs off. More soap in the water = better germ cleaning.

Soaps help water remove things that don't usually mix with water - like oils, fats and germs. The soap has one end that like water and one end that likes fat/oil/"not water". The soap surrounds the germs and the water surrounds the soap

Beyond ELI5:

A few interesting examples occur of things are NOT more soluble in hot water than cold water: triethylamine is soluble in water below 19C only. Nicotine is soluble in water below 61C and insoluble above that (weirdly, it becomes soluble again above 210C in pressurised containers). Some polymers show similar behaviour. It's called a lower critical solution temperature

The explanation for this comes down to a Gibbs Free Energy change which is too advanced for this sub.

In India, the fence will find you a donor math, there is no rules against friendly donation, so you both go to the hospital and the Indian resident signs that he is gifting you the organ(typically kidney) the doctor performs the surgery, without any risk to licence because the deal is done between the patient and the donor through the fence. The patient pays the fence( 3-5k American) and the en the fence pays the donor. Usually the donor is promised 3-5k which is life changing to their families, but after donating the kidney, the fence usually keeps most of not all the money and leaves donor with either nothing or something like 300$ and without an organ. Very lucrative market. Source-documentary on Netflix

When a solid dissolves in a liquid, it basically becomes liquid. This is kind of like melting - the solid becomes a liquid. For this to happen, the chemical bonds holding the solid together have to break. Breaking the bonds takes energy - this can come from heat, so when a substance melts it cools the area around it. The same happens when a solid dissolves - it cools the liquid around it.

However, there is a big difference between melting and dissolving. When a solid dissolves in a liquid, it becomes part of the liquid by bonding with the liquid molecules. This creates new bonds and making these new bonds releases energy as heat. This refunds some of the heat used to break up the solid in the first place.

For most solids, the heat refund is less than was paid to break the solid up. This means that dissolving costs energy and eventually you reach a balance where no more will dissolve. If you add more heat, there is more energy available and the balance points moves so that more ends up dissolved.

For some solids, the refund is actually more than was paid. In this case, adding heat reduces solubility bexause the energy balance point moves the opposite way.

The same thing happens with gases. They have super weak bonds when gases, and the bonds when dissolved are stronger, so you get an energy refund when they dissolve. Putting more energy in moves the balance point to reduce solubility.

Iirc China executes condemned prisoners on certain dates during the year, and they sell their organs on the world market.
I heard this some years ago, so I don’t know how true it is however if they bill your family for the cost of the bullet they shoot you with (which is true) I can’t see them passing up the revenue

Nope. The claim was never that.

Illegal organ trade happens across the world, even in developed countries. Never contested that.

The OP for this thread stated that people in "third world countries" blatantly post public ads offering their kidneys. That was my point of contention. Since kidney trade (with a monetary benefit) is legal in only Iran and the ad thing is quite common there.

Although cameras are different from TVs in the way pixels are counted:

  • A 4K TV has 8 megapixels in one sense but in fact each pixel is made up of three sub-pixels (red, green and blue) so really there are 24 megapixels.

  • A 24-megapixel camera is usually made up of 12 million green pixels, 6 million red pixels and 6 million blue pixels.

This makes it hard compare resolutions. Certainly an 8-megapixel video camera has a lower resolution than a 4K TV but consumer video standards (with 4:2:0 colour subsampling) reduce TVs' advantage.

The normal term for "the burden of working with rubbish code that is hard to understand or change" is technical debt.

One of the advantages of calling it that is that it sounds sort-of like financial debt, so you're putting it in language management might find easier to understand. You ideally want some concrete motivation though, like

>"technical debt will make it slower (and therefore more expensive) to add these features you want, but if we invest in reducing our technical debt first, those features will arrive sooner and have fewer bugs."

If they don't have any bugs to fix or features to add, this obviously doesn't help you much!

It's not happening in "third world countries" - it happens only in Iran.

And it's not like you said - they go in as volunteers after receiving the payment.

They have a centralized matching system, which sets a fixed price of $4.6k per kidney.

Read a little more.

Edit - For all the downvoters. This message is specifically about the comment at the top of the thread that says "it's common to find advertisements in third world countries for kidneys" and not about the illegal kidney trade, which unfortunately is extremely rampant.

I remember GOTO in combination with line numbers made maintaining or adding new features in Basic a nightmare. It's hard to tell which lines are being jumped into, meaning that by changing a line of code, you can invertedly break the program flow if you are not paying close attention to any gotos pointing at it.
To avoid this, you avoid changing any existing code that works by jumping around it. All this jumping around then results in a difficult to follow flow.

Using a bad but simple example of spaghetti code:

10 let a = 10

20 let b = "spaghetti"

30 print b

40 let b = "pasta"

50 let a = a + 10

60 if a < 60 then goto a

70 print "code!"

While clever, "spaghetti" shouldn't be printed twice. The right thing to do is rewrite this entire block of code, but you can't really do that if this is part of a larger program with other parts jumping into it as you could risk breaking other parts of your program.
So instead, using the above method of coding around problems, a bug fix could end up looking like this:

10 let a = 10

20 let b = "spaghetti"

30 goto 50

40 let b = "pasta"

50 print b

55 let a = a + 10

60 if a = 20 then goto 40

70 print "code!"

Not very pretty at all.

GMT is now ambiguous and there's nothing official that says what it means. In science, UTC has taken over as the main time standard, based on atomic clocks. The old definition of time used by GMT has been superseded and it's no longer clear what it might mean, though any of several standards based on the rotation of the earth, like UT1 and UT2, could be used.

The name GMT is still used by the British public to refer to the civil time used when summer time is not in effect. But there's no law or regulation that gives a definition of GMT or even how civil time is defined in the UK. The British body responsible for civil time has taken the obvious course and uses UTC.
