Question

sequence of thermal diffusivity in solid, liquid and gas?​

Answer 1

Answer:

The thermal conductivity of gases and liquids is therefore smaller than that of solids. In heat transfer analysis, the ratio of the thermal conductivity to the heat capacity is an important property termed the thermal diffusivity , which has units of m2/s.
