I have searched google and found no answer, does heat repel heat?

if the answer is yes, does the cold attract heat?

[chiralSPO]

Heat and cold are not substances or things. As such they cannot be attracted or repelled.

Temperature can be thought of in many different ways, but I think the easiest to grasp is thinking of it as indicative of the random kinetic energy of the atoms and molecules of whatever you are measuring the temperature of. The atoms in hot substances are moving much more than the atoms in cold substances. When I say random, I mean that if you're measuring the temperature of a glass of water, it doesn't matter how fast the glass is going--if all of the atoms are moving together, that kinetic energy doesn't count. It's the atoms that are jiggling and bouncing around in all different *random* ways.

So heat can't repeal heat, but heat does tend to spread. If two objects that are different temperatures are brought into contact (unless there is something funny going on, like a chemical reaction) the warmer one will cool down and the colder one will heat up until they are the same temperature.

It's such a shame that you refuse to take our advice and learn physics. Had you done so then you'd know that heat is thermal energy in motion. You appear to be confusing heat with thermal energy. And as a result they neither attract nor repel (since they aren't "things").

Box, mate... please read it! 'http://www.thenakedscientists.com/forum/index.php?topic=54568.msg452297#msg452297'

Box, you are lucky to be getting continuous chiding just for the sake of your own education/good. Even more lucky since that man, Mr. Peter, who's trying to teach you something... is a world class physicist! Granted he wasn't quite able to make it to Wikipedia (Be famous) due to his disk disease (And I respect him still trying to share his knowledge with us while learning more of his passion... Physics). But, the kind of knowledge he has, you should just try your best to get some of it from him while you can.
Box, you should definitely  read the thread I posted the link of in my previous post i.e.,

Box, mate... please read it! 'http://www.thenakedscientists.com/forum/index.php?topic=54568.msg452297#msg452297'

And also read some of Mr. Peter's work, here 'http://home.comcast.net/~peter.m.brown/' it's truly brilliant!
Might it be only after reading his work will you respect him and stop trying to argue with him;
 Even I just started learning QM and I have already made some theories but I have made it a rule that till the time I won't properly understand all aspects, I won't try to validate my theories... or try to prove something that I have learnt, wrong. Because, I know it's the lack of knowledge that is causing the need for me to create theories. When, if, I complete my knowledge I will understand that most of the things I thought were unexplained or needed a new theory of, already had a better explanation. Although, even if that's not the case... even If I did have a better theory. I will still wait till I complete my understanding of QM and then present it;

Mmm, well a number of us do argue with him and as long as we make sense he enjoys it.
When you don't get respect is when you argue a point without knowing the subject and just assuming everyone else has got it wrong.

I've been learning science for a long time and I'm still learning, often modifying what I thought I knew.
Long may it continue.

Well Mr. Colin (...or would you prefer Dr.?), for one to argue he must have the knowledge to keep up to the argument. I don't believe the box is knowledgeable enough to yet argue with any of you.
By the way, I'm 17 and less knowledgeable than any of you as of this moment. Hence, I use Mr. as a prefix to mostly everyone's name on here. Hope it didn't offend you.

I don't understand what you mean by this, Please explain. You may not be aware of it but I created a company to work physics out of. It's called New England Physics and is online at http://www.newenglandphysics.org/  During my convalescence I still worked in physics, I just didn't get paid for it. I created a website to help people understand physics. Each page was created to help someone understand something. I arranged the pages to make a tutorial out of them. I'll be importing that from my old site at:
http://home.comcast.net/~peter.m.brown/ to the new site and making it better in the process. It's a very long and drawn out process and will take many years to accomplish. Right now I'm in the process of reviewing all of my undergraduate courses by reading my undergraduate texts cover to cover and working all of the problems. Then I'll go to the graduate course work that I did to review that too. Then I'm going to learn new subjects like particle physics, quantum field theory and nuclear physics (full blown graduate course text). This will help me be a very good tutor for hire. I'm tutoring one person right now. So far he loves it.

...due to his disk disease...

I actually became disabled when I contracted Leukemia. It took three years to win that battle. When I tried to go back to work I went on a job interview and herniated a disk from the walking. Sheeesh!

(And I respect him still trying to share his knowledge with us while learning more of his passion... Physics). But, the kind of knowledge he has, you should just try your best to get some of it from him while you can.

Thank you very much. That's a very kind thing of you to say!

And also read some of Mr. Peter's work, here 'http://home.comcast.net/~peter.m.brown/' it's truly brilliant!

Thanks again. How did you come to learn of that website?

That's a very wise outlook. I thought I had a good idea and studied a particular problem for about 10 years. It was only after a decade did I learn how wrong I was. Oh! What a blunder!

I suggest that before you do that you first learn the terminology of physics/science. For example: look up the difference between an hypothesis, a law/axiom and a theory. Best to learn how to use these terms correctly.

[PmbPhy]

That's because you actually know what you're talking about.

Not at all Mr Jasper, I've been called worse things in my life. By the way Dr is not one of them, I wouldn't use a false title. Also, by the way, I'm not a scientist.

When I was 17 someone said "you can learn something from anyone, no matter who they are or what their education"
I have used that as a guiding principle, many years have passed and it has served me well. Even Mr Box can teach me things.
Often the simplest of questions can make us reexamine what we really know, the very simplest are even more challenging!

Don't believe you can't teach people anything, no matter what your age, I've learnt things from my 3 yr old granddaughter. Just treat everything as a learning experience.

[guest39538]

Thank you for the replies, it is only assumption that I am not learning, I put my question in brief, members have just explained what heat is without me asking the question to any readers who not understand that heat is a product of action and reaction.

I know what heat is, I never asked what heat was.   


I asked does heat repel heat?

does cold attract heat?


I got a part answer about thermodynamics.


Regardless that heat is a product waste as such, does heat repel heat?  because metal expands, I presume heat does repel heat, although the technical conclusion in the end will change from heat to something else, heat a starting premise for debate.

Oh, I was't quite aware of that and would like to apologize for my previous claim;
Oh I so wish I could have been the one to learn from you, unfortunately I live too far away;

Awww... You got offended didn't you? I'm sorry, I'll call you Colin from now on, how about that? By the way that's a very wise thing to say! I have often learnt things from people I never quite expected from whom I could learn anything from. It's just that I'm still a kid and I have this ego to uphold which won't let me learn stuff from people I believe to have less knowledge than me.

[alancalverd]

I asked does heat repel heat?

No

does cold attract heat?

No.

Satisfied?

Oh, I was't quite aware of that and would like to apologize for my previous claim;

No apologies necessary. You simply didn't know.

Oh I so wish I could have been the one to learn from you, unfortunately I live too far away;

The purpose of my company is to do online tutoring so that I can tutor anybody anywhere in the world. However it's very expensive and as such it may not be right for you.

Haha! Sorry  [] I wasn't aware of the difference. Thanks for the correction!

You're welcome.

Awww... You got offended didn't you?

No. He didn't get offended. He was simply stating a fact.

How expensive exactly?

[guest39538]

yes if thats the answer


so hot air will just merge with hot air?


added - if heat is not a thing, can it be said that heat is a state of matter?

No, not offended at all. You do me the honour of an honourific, I return the honour.

The person who said that was the workshop foreman in the first job I had, very wise. Someone else in the same workshop said, never be afraid to say you don't know, also very wise.

Sorry Mr Box, we are going off topic.
I can see why you might think that heat repels. Two objects of same temperature, no heat transfer. But it's not repulsion. Think more of 2tanks of water joined by a pipe. If the water is at the same level, it won't flow, but lift one tank to a higher level it will until both are at the same level.
Heat is like the water, temperature is like the height.

Hot air will not merge with hot air unless a wind blows them together. Although if you coloured each mass of air differently you would see some mixing because all the molecules are in a constant state of motion, the hotter, the more motion - see Brownian motion.

Heat is not a state of matter, that term is reserved for solid, liquid, gas, plasma ?etc?
Heat is more of an action, a transfer of energy, like the water between the tanks, like a ball rolling down a hill is a transfer of potential to kinetic energy. I'm sure someone has a better way of saying this as I'm just talking off top of head.

[PmbPhy]

How expensive exactly?

$50 (US Dollars) per hour

WHAT?!? It really is expensive, although surely it must be worth it;
Are you sure people will pay this amount to learn physics? I might be wrong but usually people learn things which offer good job placements and I don't believe Science offers good job placements. I mean you could probably learn Website development and get better pay. Although like I just said, I'm not sure... maybe there are descent paying jobs in Science as well, which I'm not aware of.
