Property Behavior vs. Temperature
The tabulated data shows key trends for engineering calculations:
- Density (ρ): Decreases gradually with rising temperature due to thermal expansion. The change is relatively small (~3% decrease from 100K to 1000K).
- Specific Heat (c): Increases significantly with temperature, especially above 800K. This is typical for solids as atomic lattice vibrations (phonons) absorb more energy at higher temperatures.
- Thermal Conductivity (k): Decreases substantially with temperature for iron. This is characteristic of metals, where free electron scattering increases with temperature, reducing the mean free path and thus conductivity.
