Thermal diffusivity of a substance is given by (where h = Thermal diffusivity, ρ = Density of substance, S = Specific heat, and k = Thermal conductivity) Correct Answer h = k/ ρS

Answer: Option 1

Thermal Diffusivity is defined as the ratio of heat conducted to the heat energy stored per unit volume of a material.the thermal conductivity of a substance divided by the product of its density and its specific heat capacity.Thermal diffusivity of a substance is given by h = k/ ρS (where h = Thermal diffusivity, ρ = Density of substance, S = Specific heat, and k = Thermal conductivity)
