Metals tend to be
A
good conductors of heat
B
brittle
C
dull
D
gases
Explanation: 

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 have valence electrons that are free to move around the surface. When heated, these free electrons collide with each other and the majority of the Kinetic energy is transformed into heat energy, making metals a good conductor of heat.

Detailed explanation-4: -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-5: -Which Metals Conduct Heat The Best? As you can see, out of the more common metals, copper and aluminum have the highest thermal conductivity while steel and bronze have the lowest. Heat conductivity is a very important property when deciding which metal to use for a specific application.
