Your picked answer is different than what the actual results are.

Where are the details of the experiment that gave you these "actual answers"?

Definitions involve assumptions.

Wrong.  A definition is an absolute statement that creates truth.

A cow is defined as a mature female bovine quadruped. No assumptions involved.

Do you have an idea how to get the first possible result, i.e. both cups retain their ice/water ratio?

Of course!  Why are you asking, haven't you read your own thread?

Here's my idea to minimize noise over signal:
- Prepare 50/50 ice-water mixture at around 0°C in a large plastic bowl. Let it in refrigerator for an hour to reach equilibrium.
- Fill a metal cup with 90% water and 10% ice from the mixture.
- Fill another metal cup with 10% water and 90% ice from the mixture.
- Put both metal cups into the bowl containing the remaining of the mixture.
- Let them in refrigerator for an hour to reach equilibrium.
- See the result, if the ratio of ice-water in the cups change.

OK. I've finished my first round of experiment as described above. But I can't get the metal cups, so I just used ordinary drinking glasses. I guess the heat conductance is enough for this experiment since they are quite thin.
The temperature of the refrigerator is 4C, as shown by a thermometer left there for an hour. The result is the ice in both glasses decreased from initial ratio.
So I moved the system to the freezer, which is kept at -4C, as measured by a thermometer left there for an hour. The result is the ice in both glasses increased from initial ratio.
These results show that energy transfer between the system and the environment overwhelmed the energy transfered through the glasses. It means that the noise over signal ratio is too high to get reliable conclusion. Hence the experimental setups need to be improved.
I also learned that gravity and buoyancy play significant role in determining the results, which need to be addressed in upcoming experiments.

You assume that someone who read your definition knows and agrees with the meaning of mature, female, bovine, and quadruped.

Nope; the definition of "cow" is still correct, regardless of whether it is understood.

The same is true of "flash point".

The ignorance or knowledge of the reader isn't relevant to the definition.

It turns out that ice-water bath is not adequate to keep the outer sides of the glasses at 0C. The ice tends to float, which makes lower part of the bath warmer, even when it's only a few centimeters deep. This temperature difference seems to cause the heat transfer through the glass.
So, obviously the next step to improve the experiment setup is to keep the ice at the bottom of the bath. Convection will make temperature of the bath more uniform around 0C.

Have you heard that someone defined pi = 3?

I'm beginning to think you enjoy the feeling of being confused.  You now seem to not even know what a definition is.  I don't get you at all.

No.
I'm aware that someone tried to.

But reality stopped them.

Why did you think that was relevant?

The object of philosophy is to tell people that they don't (or even can't) understand the obvious. I think HY is an undercover philosopher.

[alancalverd]

No. Convection requires a temperature gradient.

It seems like you missed to read this claim.

Wrong.  A definition is an absolute statement that creates truth.

That's why you didn't get it.

[Bored chemist]

Did you notice that nobody actually defined pi as 3?

It looks like you need to read the introduction to philosophy. Here's a book recommendation I got in my twitter feed.

Here's a part of the foreword.

One of the authors of this book had a teacher—
a short, white-haired, elderly gentleman with a thick German accent—who used to say, “Whether
you will philosophize or won’t philosophize, you
must philosophize.” By this, he meant that we can’t
help making decisions about these crucial matters.
We make them either well or badly, conscious
of what we are doing or just stumbling along.

No. Convection requires a temperature gradient.

That's what I found as experimental results. Ice-water mixture don't maintain homogeneous temperature. Difference in density tends to make bottom part of the bath warmer than the surface.

You can only make stuff warmer by adding energy, so that finding can not be relevant to the discussion.

Told you so.

Ice-water mixture don't maintain homogeneous temperature. Difference in density tends to make bottom part of the bath warmer than the surface.

No, difference in temperature makes one part warmer than the other, and as water is denser than ice, the warmer bit sinks to the  bottom.

It is interesting to speculate whether life would have evolved, or what it would look like,  if ice was denser than water.

May be it's not relevant to the title or theoretical consideration. But it's relevant if we want to get experimental evidence.

You will not get experimental evidence of what happens at 0C (as per the thread title) unless your equipment is at 0C.
