उत्तर
Will not absorb heat
Explanation:
Wood is a non-conductor material, which is not a good absorber of heat. On the contrary, it acts as a heat trap.
Wooden chakla absorbs heat very slowly because:
- Wood is a poor conductor of heat.
- It does not transfer heat as quickly as metals such as copper or iron.
- Wood has small air pores inside it, which prevent the flow of heat.
