Meaning and Definition
The movement or separation of particles in a mixture due to a temperature gradient.
A physical process, also known as the Soret effect, where a temperature difference in a fluid mixture causes a concentration gradient, leading to the separation of components.

- Using it as a general term for any heat-related movement. Confusing it with thermophoresis (which often refers to particle movement in response to a temperature gradient in a gas).
FAQ
Frequently Asked Questions
Yes, thermodiffusion is precisely the Soret effect. The terms are synonymous in scientific literature.
Almost exclusively in advanced scientific texts, particularly in journals and books on transport phenomena, fluid dynamics, or separation science.
No, it is a highly technical term with no application in general conversation or non-specialist writing.
A temperature gradient (a difference in temperature across a medium) is the sole driver of the thermodiffusion process.
The movement or separation of particles in a mixture due to a temperature gradient.
Thermodiffusion is usually technical/scientific in register.
Thermodiffusion: in British English it is pronounced /ˌθɜː.məʊ.dɪˈfjuː.ʒən/, and in American English it is pronounced /ˌθɝː.moʊ.dɪˈfjuː.ʒən/. Tap the audio buttons above to hear it.

Memory Aids
Mnemonic
Think: THERMO (heat) + DIFFUSION (spreading/mixing). It's the 'diffusion' or separation caused by 'heat' differences.
Conceptual Metaphor
HEAT AS A SORTING FORCE (Heat acts like a sieve or a magnet, pulling different particles to different sides).
