Equally irrelevant. Heat flows from a higher temperature body to a lower temperature body, regardless of their specific heat capacity or heat content per unit mass.

It's relevant to answer your previous comment.

Heat transfers from a hotter body to a colder one, nothing to do with the heat content of either.

If it were otherwise, you would boil every time you (70 kg of water at 37°C) swam in the sea (bazillions of tonnes at 17°C)!

So, for about the 4th time, what do you think it is in the case of the ice and water?

Entropy.

23 pages and you still can't understand that heat flow is from hot to cold.  Keep trying and maybe you can get it!

Entropy.

That can't be right; it's an intensive property.
https://en.wikipedia.org/wiki/Intensive_and_extensive_properties
(This is, of course, another example of why I think it would be better if you learned physics rather than posting 23 pages of misunderstandings.)

But, I'm curious.
How did you imagine it would work?
How would "entropy" be the property that went up + down in the right way?

[hamdani yusuf (OP)]

Entropy is an extensive property.
But we can get a closely related intrinsic property by simply divide it by the object's mass. Let's just call it specific entropy, analogous to specific weight, specific heat capacity, etc.

A system of a container with ice on one side and water on the other side has low entropy.
A system of a container with equal mixture of ice and water on both sides has higher entropy.

Here's an analogy. Take a container with two compartments. Left compartment is filled with sugar solution. Right compartment is filled with salt solution. Take out the separator. Diffusion will make both compartments eventually reach equilibrium with equal ratio of salt and sugar. Each sugar molecule doesn't have to know where the other sugar and salt molecules are at any time. The equilibrium will be reached naturally by statistical mean.

Take 1 kg of Plutonium. Take 1 kg of iron with the same initial temperature. Put them in an insulated compartment. Will there be a heat flow?

How do you think Parker space probe survive in sun's corona?

You think that you already understand something by simply ignoring cases where you are not familiar with.

The Plutonium will increase in temperature due to spontaneous decay and the heat will flow from the higher temperature Plutonium to the lower temperature iron, just like you have been told innumerable times.

Insulation.

I'm not ignoring anything, the physics is actually quite easy on this subject and the answer to the OP remains the same as was stated on the first page, "there is no net heat exchange".

[hamdani yusuf (OP)]

Insulation.

Has it reached thermal equilibrium with its surrounding?

[hamdani yusuf (OP)]

The Plutonium will increase in temperature due to spontaneous decay and the heat will flow from the higher temperature Plutonium to the lower temperature iron, just like you have been told innumerable times.

You are ignoring heat generated in iron due to impact by emission from radioactive decay.

[Bored chemist]

Insulation.

Has it reached thermal equilibrium with its surrounding?

Not yet, which makes it irrelevant.
Why did you mention it?

Yes I am, it's irrelevant.

[hamdani yusuf (OP)]

If it's not in equilibrium yet, then its temperature will increase. Will it have the same temperature as its environment?

Yes I am, it's irrelevant.

My point is, that temperature difference is not the only parameter that can drive material/energy transfer. Some other parameters are known to cause material/energy transfer, such as differences in electromagnetic potential, gravitational potential, and entropy.

But, I'm curious.

Why are you trying to change the subject, you know we are talking about heat not "material/energy transfer".  The one constant in your posts is that when you ask a question you will never accept the answer.  I really don't 'get you'.

I'm not trying to change the subject. I'm trying to remind you that there are other factors besides temperature that can affect experimental results which haven't been ruled out properly/convincingly.

It is a common practice in science where one answer generates more questions. Get use to it. Even more questions will come up when the offered answer is not convincing.

Heat is one form of energy. In another thread I discussed what distinguish heat from other forms of energy.
It was also mentioned previously that heat is not identical with temperature. Heat can be added to an object without changing its temperature. Temperature can be seen as a manifestation of heat.

They generally have been by those people who do proper, convincing experiments.   

Once more: heat experiments are very difficult.

Yes, I have run many experiments, hopefully we all know that other factors must be taken into account.

It is a common practice in science where one answer generates more questions. Get use to it. Even more questions will come up when the offered answer is not convincing.

Unfortunately your questions are largely irrelevant and just confuse you.  Your questions and doubts seem to paralyze you and you can't seem to move forward.

Heat is one form of energy. In another thread I discussed what distinguish heat from other forms of energy.

That's great but in this thread the question is, "Is there a net heat exchange between ice and water at 0C?"  The answer is no, but for some reason you can't see that so it seems kind of important to stay on track.

It was also mentioned previously that heat is not identical with temperature.

I would certainly hope that someone with a basic knowledge of physics would know that heat and temperature are two completely different things.

Heat can be added to an object without changing its temperature.

True.

Temperature can be seen as a manifestation of heat.

Heat can change the temperature of matter if that's what you mean.

[hamdani yusuf (OP)]

Heat can change the temperature of matter if that's what you mean.

Heat can also change the phase of matter without changing its temperature.
