Thermal diffusivity is
A. A dimensionless parameter
B. Function of temperature
C. Used as mathematical model
D. A physical property of the material
Answer: Option D
Solution(By Examveda Team)
Thermal Diffusivity is defined as the ratio of heat conducted to the heat energy stored per unit volume of a material.Its SI unit is m2/s.
It describes how fast heat can be transferred across the medium.
Greater the value of thermal diffusivity, faster is the propagation of heat through the medium.
