Mechanism of Heat Conduction in Solids:
Heat conduction in solids is primarily due to two mechanisms:
- Phonons: Phonons are quantized lattices vibrations and play a major role in conducting heat in non-metallic solids. Even in metals, phonon interactions contribute to thermal conductivity.
- Electrons: In metals and conductors, free electrons significantly contribute to heat conduction due to their mobility and ability to transfer energy across the lattice.
Other options:
- Protons: Protons are confined within the atomic nucleus and do not participate in heat conduction in solids.
- Photons: Photons are particles of light that can transfer heat via radiation but not conduction in solids.
So the generalized context of heat conduction in solids, the correct answer is phonons
