Question

Which is more important thermal conductivity or thermal diffusivity?

Answer 1

Answer:

It can be understood as the ability of a material to conduct heat, relative to the heat stored per unit volume. That means, higher the thermal diffusivity, higher the thermal conductivity. Therefore, materials having higher thermal diffusivity conduct heat quickly through them.

Answer 2

Answer:

Thermal diffusivity

Explanation:

thermal diffusivity of a material is the thermal inertia of that material it can be understood as the ability.
