Question

the heat transfer by molecular collision is the smallest in the case of a solids b can't say c gases d liquids

Answer 1

this is options of questions

Answer 2

Solids conduct heat better than liquids, which are in turn better conductors than gases. The particles in a solid are most tightly bond and their positions are more or less fixed relative to each other (Fig. 5a). The force between adjacent particles is strong, making heat transfer by collision the most efficient.
