Question

Heat conduction in glass is due to

Elastic impact of molecules
Motion of electrons
Mixing motion of different layers of gas Electromagnetic waves​

Answer 1

Answer:

The appendix may be the most commonly known useless organ.

Answer 2

Explanation:

In fluids (liquids and gases), the heat conduction is a result of diffusion and intermolecular collision. But in case of gases, due to low density and high root mean square velocity of molecules the rate of diffusion is much more dominant then intermolecular collision. But in the options diffusion is not mentioned thus elastic impact of molecules due to inter molecular collision is the correct answer.
