Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
An element that is a good conductor of heat and electricity is a ____
A
metal
B
non-metal
C
metalloid
D
noble gas
Explanation: 

Detailed explanation-1: -Gold, Silver, copper, and aluminum are a few examples of good conductors of heat and electricity.

Detailed explanation-2: -For example, metals are good conductors of both heat and electricity, whereas nonmetals generally cannot conduct heat or electricity.

Detailed explanation-3: -Metals are good conductors of heat and electricity, and are malleable (they can be hammered into sheets) and ductile (they can be drawn into wire). Most of the metals are solids at room temperature, with a characteristic silvery shine (except for mercury, which is a liquid).

Detailed explanation-4: -Metals like copper and aluminium have the highest thermal conductivity while steel and bronze have the lowest. As copper is an excellent conductor of heat, it is good for heat exchangers also. Example: Gold, Silver, Iron, etc are some examples of good heat conductors and electrical conductors.

Detailed explanation-5: -Q. Mica is a good conductor of heat, but a bad conductor of electricity.
