Identify the correct statement for conduction?
DSSSB - 2023,
Answer: C
In solids, conduction may be attributed to atomic activity in the form of lattice vibrations, along with the movement of free electrons in metals. This is the statement the key accepts. Conduction is a microscopic mechanism and not a macroscopic form, in fluids it occurs from collisions and diffusion of molecules in their random motion, and the basic equation of conduction is Fourier's law, not Maxwell's law. The second option is also a textbook statement but the key names the third.
