Question

can you explain why heat transfer cannot take place by the process of convection in solid substance?​

Answer 1

Answer:

Explanation:

Liquids and gases expand when they are heated. This is because the particles in liquids and gases move faster when they are heated than they do when they are cold. Convection cannot happen in a solid because, like the bricks in a wall, the atoms in a solid cannot move far from where they are.
