Detailed explanation-1: -The reason metals conduct heat so well is because the electrons in them can move around easily, and they can carry heat from one part to another. Metal atoms are packed more densely and can transmit heat vibrations more readily.

Detailed explanation-2: -Metals are particularly good conductors of heat because their particles are very closely packed so the vibrations are passed on very quickly. They also contain large numbers of free electrons. These drift slowly through the structure, giving metals their strength and other properties.

Detailed explanation-3: -Metals are excellent conductors of electricity and heat because their atoms form a matrix through which outside electrons can easily move. Instead of orbiting their individual atoms, they generate a sea of electrons around the positive nuclei of the interacting metal ions. To some extent, most metals carry electricity.

Detailed explanation-4: -Generally, metals are good conductors of heat but poor conductors of electricity.

Detailed explanation-5: -Answer: Solution: (a) True; Metals are good conductors of electricity. So, an electric current can easily flow through them.
