Question

Difference between thermal conductivity and thermal diffusivity

Answer 1

Answer:

1. Thermal conductivity is a thermophysical measure of how much heat is transferred through a material by the conductive flow. ... According to thermodynamics heat flows from warmer to cooler regions. Thermal diffusivity controls the time rate of temperature change as heat passes through a material.
