Convection cannot take place in solids because___________
Convection cannot take place in solids because___________
The correct option is A actual movement of particles is not possible
In the process of convection, molecules move vertically upward after getting heated up.
Explanation of the correct answer
Option A- actual movement of particles is not possible
1. In solid the molecules are closely packed and hence the movement of particles is not possible.
Explanation of the incorrect answer
Option B- solids possess free electrons
1. Although, the solids can possess free electrons, but free electrons can be responsible for the conduction of electricity.
2. Free electrons cannot be responsible for convection.
Option C- atoms are loosely packed
1. In solid the atoms are closely packed.
Option D- they are bad conductors
1. Solid can be both a good conductor as well as a bad conductor.
2. Convection doesn't depend upon whether the material is a conductor or not.
Hence, option A is correct.
