What Is Heat

[SSDD]

I have recently been in an ongoing discussion with some members of the forum about energy transfer...movement from warm to cool..etc. It doesn't take long for the conversation to move from one of evidence to one of what science "knows".

Good question don't you think....what does science know.

Heat, I would guess is the cornerstone of the global warming, AGW discussion. So lets look at that cornerstone and ask "What is heat?" Is heat a form of energy, or is heat the fingerprint, or signature of energy moving from one place to another?

What does science say?

Science Daily says: Heat

In physics, heat is a form of energy associated with the motion of atoms, molecules and other particles which comprise matter

So heat is a form of energy.

The physics department at the University of Maryland says: http://www.physics.umd.edu/courses/Phys260/agashe/S10/notes/lecture11.pdf

Heat: energy transferred between system and environment; heat is not a form of energy or state variable; heat can cause thermal energy to change

So heat is not a form of energy.

The Physics Classroom says: What is Heat

Heat is a form of energy that can be transferred from one object to another or even created at the expense of the loss of other forms of energy.

So heat is a form of energy.

The Grandinetti Laboratory Teachers Reference on Thermodynamics says:
Thermodynamics

Just like work, Heat is not a form of energy, but rather, is an energy transfer process.

So heat is not a form of energy.

The Chemistry Department at the University of Arizona says:
Energy Work and Heat The first Law

One of the great breakthroughs in the history of science was the recognition that heat is a form of energy.

So heat is a form of energy.

The Lecture Exchange - Physics for Scientists and engineers says:

Heat Is Not a Form of Energy. The word heat is one of the most misused words in our popular lan- gauge.

So heat is not a form of energy.

Hands on Physics says: Heat and Temperature- Concepts

Heat is a form of energy, so it has the units of energy

So heat is not a form of energy.

The Factmonster says: HEAT FactMonster.com

Heat is a form of energy

So heat is a form of energy.

And I could go on at some length providing credible scientific sources claiming that heat is a form of energy and that heat is not a form of energy. Here we stand, nearing the end of the 14th year of the 21st century and science remains unsure of what, precisely, heat is.

For all of you out there who believe that science somehow knows all...knows what photons are doing, or even knows whether photons exist or not...or knows that at the microscopic level that energy transfers between objects in two directions even though it has never been observed out here in the real world...or believes that science knows whether light is a wave, or particles, or either...or any of the literally hundreds of things that people here have claimed that science knows rather than science thinks, or science believes...or science theorizes or science hypothesizes...consider the fact that today, science doesn't even know what heat is.

Any of you geniuses out there want to say what heat is? Clearly science doesn't know....and if science does't know what something as basic and fundamental as heat is, what else doesn't science know?

Wow thats stunning. Even the AGWCult has consensus that a wisp of CO2 will raise temperature from 2-7 degrees and drop ocean pH from 8.25- 8.15

Right now science is just beginning to learn how much it doesn't know

I thought the heat were those guys you avoided when you were carrying.

 

[SixFoot]

Heat is what happens when you burn firewood.

 

[IanC]

Heat is what you feel when you watch the girls playing beach volleyball in their bikinis. A different kind of wood.

Would you have thought that here, in the 21st century science would still not be able to unanimously state what heat is? If they remain unsure as to exactly what heat is, the idea that they are sure what goes on at the microscopic is just silly.

Wow SSDD -- 3 post now? And you're still on solid scientific ground? Congrats bro !!!

HEAT only propagates by conduction and convection in materials, but HEAT also causes materials to GLOW and radiate ENERGY..

Let's go from there...

 

[flacaltenn]

I'm telling ya man.. All that Glowing and Radiating was hardly covered in basic Thermo.. Ain't your fault !!!! The profs decided undergrads would be lost calculating surface radiation patterns and geometry..

Speaking of heat in relation to co2, it is worth noting, the interaction between the two is impossible to observe or measure.

Everything is conjecture, an idea, a hypothesis.

What was the last science class you took Mr Business Major?

 

[Crick]

No you haven't. An "ongoing discussion" would required that you read and understand what's being said to you. The posts you refer to fail that basic test. People have been lecturing you and you've been ignoring them. That's not a discussion.

What a fucking idiot.

 

[HenryBHough]

Heat.

That's what prudent people pack when venturing into certain neighborhoods.

Also that which California elected federal senators and representatives pack to show you're not to be allowed to.

My job, technically speaking, is pure Science. My last class, scientifically speaking was two weeks ago for the customer I consult to, Ontario Hydro. Pickering would be the plant I am providing my consulting service to.

I think heat is easier to understand when you learn about potential and kinetic energies.

 

[HenryBHough]

Believe it or not, my understanding those equations and being able to apply them once got me hired for a job over six other applicants all of whom had more "education".

Is heat energy?

The distinction is semantic. Heat is a tactile sense of temperature differences.

The physics is always the same.

Impedance curves, inductive reactance, hysteresis and eddy current analysis.

I also learned of inductive reactance while studying electronic radio engineering.

Heat IS energy -- measured in Joules or the equivalent. And it is based on both stored and kinetic components. Go ask Obama for a definition of kinetic actions. It means dropping bombs and firing weapons. Stay away from any kinetic actions that involve heat. Just tied up Henry's heat definition nicely here.

Important part here for the topic is that materials lose or gain heat by conduction, convection or photon radiation.. Like they say on the Sesame Street -- "Two of things are not like the other"...

Heat is what happens when you burn firewood.

Heat is the buy product of molecular movement. As molecules move they create friction, friction warms the molecules, they then radiate heat in the form of infrared radiation.
