If the thermal conductivity of a wall material is independent of temperature, the steady state temperature distribution in the very large thin plane wall having steady, uniform surface temperature follows ____________ law?
Correct answer: C. Linear
- A. Hyperbolic
- B. Parabolic
- C. Linear
- D. Logarithmic
Explanation
For one-dimensional steady conduction through a plane wall with constant thermal conductivity, the temperature gradient is constant, so temperature changes linearly with distance. Curved distributions occur when geometry or thermal conductivity varies.
