To repeat the obvious answer to the original question: No, by definition.

How does it help to predict experimental results?

It predicts them absolutely, fully, and completely.
But only if you do a very good experiment, and that's very difficult with water. 

Geocentric model predicts planet positions accurately, as long as you add enough appropriate epicycles to it. Someone might insist that planets move around the earth by definition.

[hamdani yusuf (OP)]

Once you have "slightly warmer water" you are no longer at 0oC

The system's average temperature can be still at 0C if another part has slightly lower temperature.

Under our new system of taxation, if I have more money than you, I must give you some.

I have $1,000,000, you have $0.

You say I have more money than you, so I owe you  $500,000

I say our average balance if $500,000 so I don't have to give you anything.

If they are doing that since Foucault did a better experiment then they are not scientists.
More importantly, they would need to explain why there are epicycles.

[alancalverd]

Because God deemed it so. Who do you think you are? Galileo? Bruno? Occam?

Here's a video from Alpha Phoenix, which may provide useful information to consider in designing experiment with water and ice.

What is polycrystalline water?

Episode 2 of my series on water ice! Admittedly this is probably the least interesting because it's some negative results, but it's not very scientific to only discuss successes right? In this video, I use a lens to melt ice from the inside out, exposing it's polycrystalline structure (and explain how it's different from a single crystal). With this partially-melted ice, I can do a bit of materials forensics, and actually figure out how it formed, hopefully so I can improve the process in the future!

Next video will be on vapor growth, and I'll say right now that it DOES work to grow centimeters-big faceted single crystals! Subscribe to make sure you see it!

What do you think?

Well I'll be blowed! You add energy to ice, and it melts! Who would have thought it?

The heat generated in the center of the ice block is higher than the outer sides, even when it's farther away from the heat source.

[alancalverd]

Yes. Power density is important in all sorts of processes.

[hamdani yusuf (OP)]

Another factor to consider in determining heat generation and transfer by wave is the formation of standing wave, which usually involves reflectors. Some areas may get less heat even when it's closer to the wave source.
It can be seen in microwave ovens.

"Is there a net heat exchange between water and ice at 0 degree C?"
If you think there is, which way does it go?
When does it stop?

Here are my considerations :
Temperature is an average statistical value.
Some points in an object has more kinetic energy than another point, which vary in time.
Heat flows from points with locally-temporally higher kinetic energy to another point in thermal contact with them.
Water has higher heat content than ice, when they are at the same temperature and pressure.

You seem to have forgotten to answer the questions.

[alancalverd]

Let's try a different analogy. Consider two batteries, each with a potential of 1.5 volts. Connect them in parallel. Does any current flow from one to the other? Temperature is the thermal analog of electrical potential.

I'm afraid Hamdani Yusuf is never going to get it, he still doesn't know what temperature is...

[hamdani yusuf (OP)]

You seem to have forgotten to answer the questions.

I thought you are smart enough to conclude based on those considerations.

You don't seem to know either. At least I don't pretend to know something that I don't know.

Did you consider the idea that, no matter how smart I may or may not be, you didn't provide enough information.
So, for the third time

"Is there a net heat exchange between water and ice at 0 degree C?"

When does it stop?

All analogies break down at some points, where they don't resemble the things that they are supposed to represent anymore. Your batteries don't experience phase changes. Hence they are more like two ice blocks with the same temperature.
