Can Electrons Really Conduct Heat?

Click For Summary

Homework Help Overview

The discussion revolves around the concept of heat conduction by electrons and whether electrons possess heat capacity or temperature. Participants explore the relationship between electrons, heat, and temperature, questioning the fundamental definitions and properties of these concepts.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants examine whether electrons can conduct heat and if they have heat capacity. Questions arise about the nature of heat and temperature, particularly in relation to single particles like electrons. There is also a focus on the distinction between heat and temperature.

Discussion Status

The discussion is active, with various interpretations being explored regarding the definitions of heat and temperature. Some participants provide insights into the nature of energy transfer and the characteristics of electrons, while others express confusion about the implications of these properties.

Contextual Notes

Participants note the challenge of discussing heat in the context of individual particles, raising questions about the absence of internal structure in electrons and its implications for thermodynamic properties.

Can an electron conduct heat? I know electrons are partially the reason why metals conduct heat, but can an electron itself conduct heat? In other words, does an electron have a heat capacity?

What is "heat"?
Does it make sense to talk about the heat of a single particle?

Electrons can carry energy from place to place - they may gain energy from heat, get ejected, travel to some place where it is captured, transferring it's energy to the system as heat ... so the electron has conducted heat.
 
If electrons conduct heat, then do they have a heat capacity? Also, I just noticed I posted this on the mathematics section. Haha

Does a single molecule or atom have heat capacity?

What is heat?
 
Well temperature is the average kinetic energy of particles in a substance. Consequently shouldn't heat be almost the same thing?

Temperature & heat are related, but they're not at all the same thing.
 
Well heat is the energy transferred between two materials. But heat can only be transferred between two objects if the objects have atoms and molecules to absorb the energy to use as kinetic energy. How does an electron get a raise in temperature if it doesn't have any sub sub atomic particles to pass on the heat energy?
 
What I mean to say is, can an electron have temperature?

Isn't that the answer to your question? An electron can have kinetic energy, but that's about all. It doesn't have any component parts. So it can't have a temperature. It can't absorb or release any 'internal' energy. It doesn't have any.

Temperature is the average kinetic energy of a materials particles. Since the electron doesn't have any "particles", it has
no temperature. Is it just me or is that strange thermodynamically? If a material doesn't have a temperature, what is the "stuff" that makes the electron? For neutrons and protons its a different story because they have quarks. What about the electron? Does having no temperature mean zero kelvin or something else?

As far as anyone knows to date, an electron has no parts inside of it. If you connect an electron to a heat bath of any temperature it won't absorb heat or give it up. It has no temperature. That's not the same as zero kelvin.
