Correct Answer: ✅ Vacuum

Explanation:

A vacuum is a very poor conductor of heat because it contains no particles. In a thermos flask, the space between the inner and outer walls is a vacuum, which prevents heat transfer by conduction and convection, helping maintain the temperature of the liquid inside.

Why other options are incorrect:

• Wood – Poor conductor, but not used between flask walls.

• Cloth – Acts as insulation but cannot prevent convection completely.

• Water – Conducts heat and would increase heat transfer.
