Answer:

From the formula of Biot number, it can be defined that its value is inversely proportional to the thermal conductivity of the body. Thus, with a larger value of k, the Biot number will be lesser. Hence, due to lower thermal conductivity, the value of the Biot number will be larger for poorly conducting solids.
