Answer:
Convection occurs when thermal energy is transferred by the movement of fluid particles.
Explanation:
Transfer of heat energy by the movement of fluid particles is called convection. Convection takes place in liquids and gases due to kinetic energy. When heat is provided to liquids and gases they expand and move faster.
Molecules with higher kinetic energy become less dense and rise up to the surface of liquid, whereas molecules with lower energy move towards the bottom. This up and down movement of molecules causes convection currents in fluids.
I'm pretty sure it would be A. As fluids are able to move and flow pretty easily.
The correct answer would be A
1.Phases - Gas, liquid and solid. Gas, liquid, and solid are known as the three states of matter or material, but each of solid and liquid states may exist in one or more forms.
