Answer 2

Answer:

two good conductors of heat are iron and copper

two insulators of heat are plastic and rubber

Explanation:

Applications of Conductors

Mercury is a common material in thermometer to check the temperature of the body. Aluminium finds its use in making foils to store food. It is also used in the production of fry pans to store heat quickly. Iron is a common material used in vehicle engine manufacturing to conduct heat.

Insulators work as protectors. They may protect heat, sound and the passage of electricity. Thermal insulators, sound insulators and electrical insulators are used for various reasons, from keeping houses warm to protecting electrical wires and soundproofing rooms.
