Question

why is heat transfer by Convection possible only in liquid and gases​

Answer 1

Answer:

Convection is a type of heat transfer that can only happen in liquids and gases, because it involves those liquids or gases physically moving. Convection happens when there is a difference in temperature between two parts of a liquid or gas. The hot part of a fluid rises, and the cooler part sinks.

Answer 2

Hello,

Because in solids, the particles are very tightly packed with each other, so they have very less or no Kinetic energy. So the transfer(moving) or the conduction of heat is impossible In solids. Whereas in liquid or gases, they are having free spaces between the particles, and more kinetic energy, so that the heat energy can. Move and conduct easily.
