The correct answer is Lead. Among metals: Copper & Zinc are good conductors. Mercury metal is a poor conductor while Lead is the poorest conductor.
Which type of material is a poor heat conductor?
In general, good conductors of electricity (metals like copper, aluminum, gold, and silver) are also good heat conductors, whereas insulators of electricity (wood, plastic, and rubber) are poor heat conductors. The figure below shows molecules in two bodies at different temperatures.
What material is the poorest conductor of heat?
Metals and stone are considered good conductors since they can speedily transfer heat, whereas materials like wood, paper, air, and cloth are poor conductors of heat.
What are the poorest conductors?
Bismuth and tungsten are two metals which are poor conductors of electricity. Dear friend, Tungsten and Bismuth are metals which are poor conductors of electricity. Stainless Steel is a poor conductor because it has an alloy structure.
Which metal is the best conductor of heat?
Is lead a good insulator for heat?
Lead Conductivity
“Although lead compounds can be good insulators, pure lead is a metal that conducts electricity, making it a poor insulator. Lead’s resistivity is 22 billionths of a meter. … For example, the connectors for car batteries are typically made of lead.
What are 5 good conductors of heat?
Some materials allow the heat to flow through them and they are known as good conductors of heat or heat conductors such as iron, aluminum, copper, silver, brass, lead and stainless steel.
What kind of materials are good conductors of heat?
Metals and stone are considered good conductors since they can speedily transfer heat, whereas materials like wood, paper, air, and cloth are poor conductors of heat. These conductive properties are rated based on a “coefficient” which is measured relative to silver.
Which metal is bad conductor of heat and electricity?
Although metals are supposed to be good conductors of electricity and heat,metals like mercury, lead, alloysof iron and chromium, titanium andstainless steel are poor conductors when compared to silver, copper and gold.
Which is the best conductor of heat and electricity?
Silver is the best conductor of heat and electricity.
What are the bad conductors?
Materials that are poor conductors of electricity are called insulators. Some examples are wood, glass, plastics, non-metal elements that are polymers of hydrocarbons.
Is titanium a good conductor of electricity?
Electrical Conductivity and Resistivity.
Titanium is not a good conductor of electricity. If the conductivity of copper is considered to be 100%, titanium would have a conductivity of 3.1%. … For comparison, stainless steel has a conductivity of 3.5% and aluminum has a conductivity of 30%.
Does aluminum heat up faster than steel?
“1kg of Aluminium requires twice as much energy to raise its temperature than 1kg of steel. However, aluminium has a larger thermal conductivity than steel. If a hot coin is placed on both an alminium slab and steel slab of same mass, which coin will cool faster.”
What metal has the highest heat capacity?
Is Diamond a good conductor of heat?
Unlike most electrical insulators, diamond is a good conductor of heat because of the strong covalent bonding and low phonon scattering. Thermal conductivity of natural diamond was measured to be about 2200 W/(m·K), which is five times more than silver, the most thermally conductive metal.
