w m.K A novel strontium-silica glass has a thermal conductivity 1 of 2.1 (exceptionally high for a glass). Approximately, what would you expect the thermal diffusivity will be? Use the empirical relation in the lecture slide. Where would it lie on thermal conductivity -thermal diffusivity (k - a) chart given below? Use the chart to indicate the material's class.
