Not so much plastic and wood.

. Silver also has the highest thermal conductivity of any element and the highest light reflectance. Among the following materials which is the best conductor of heat. Brilliant light is seen at the target.

Heat is generated at the target. Solids are generally very good conductors of heat. Rate of heat flow tQ.

The best conductor of heat among the following is-. Metals like copper and aluminium have the highest thermal conductivity while steel and bronze have the lowest. The block of iron is heavier than the wooden block.

Iron is a bad conductor of heat in comparison of the wood. The temperature of the iron block is less than that of the wooden block. Silver and copper are excellent conductors of both heat and electricity.

Thermal conductors are materials that heat passes through easily. In a molten state the bonds become much weaker causes high increases in kinetic energy. Gold and copper both come near to silver respectively and with copper being considerably less expensive in many applications it is often preferred over the silver.

Mercury has the highest thermal conductivity of 830WmK among given options so it is the best conductor of heat. Many metals like silver copper gold and aluminum are good thermal conductors. Conduction or the transfer of heat can take place within a single material or between two objects.

The best conductor of heat among liquids is Mercury. The Greek name of mercury is hydrargyrum from where its symbol is taken. It is the only metal that is liquid at standard conditions for temperature and pressure.

The temperature of the target remains constant. Silver Metal with a thermal conduction value of approximately 430 w mk. Heat is transferred from the warm surface of the Earth to the cooler overlaying troposphere via.

As copper is an excellent conductor of heat it is good for heat exchanger also. Heat is absorbed at the target. We know that metals can conduct electricity in solid and molten states.

As copper is an excellent conductor of heat its good for heat exchangers heat sinks and even saucepan bottoms. The electrons can move more freely having a higher capacity to conduct electricity. Metals are good conductors of heat.

Metals are good conductors. Leave a Comment on The best conductor of heat among the following is. Heat can only travel from a hot material to a cold material.

It is the only metal element to exist in the liquid state at room temperature ie. Heat is conducted within and between. The best conductor of heat among the following is.

Alcohol is a class of organic compounds in which one or more hydroxyl -OH groups attached to a carbon atom of an alkyl group hydrocarbon chain. The best conductor of heat among the. Where k is thermal conductivity A is the cross-sectional area of material l is the length of the material.

It does not travel in the opposite direction. A metal spoon would be the best conductor of heat energy because metals primarily conduct heat as it is one of their physical properties. So higher the thermal conductivity higher is the rate of heat flow.

Iron is a good conductor of heat in comparison of the wood. Mercury The correct answer is Mercury. Because steel is a poor conductor of heat its good for high-temperature environments like airplane engines.

Mercury is a heavy silvery-white liquid metal. The most electrically conductive element is silver followed by copper and gold. Electronic devices Communication system.

The-best-conductor-of-heat-among-the-following-is SingleChoice 5e2536a24f019a6cc27ccf74 4. Length of the wire only but neither on the area of cross-section of the wire nor on the material of the wire. Gold Silver Iron etc are also some examples of good heat conductors as well as electrical conductors.

In Everyday Science MCQs Set-15. At night the ground surface often is. There are different types of conductivity including electrical thermal and acoustical conductivity.

Among the best conductors of heat and electricity is silver. Correct Answer - Option 3. Alcohol is a bad conductor of heat and electricity as it does not ionize.

Although it is the best conductor copper and gold are used. Which of these materials is the best conductor of heat. When X-rays are produced.

Since mercury is 13 times as dense as water a given volume of mercury would carry about 44 times as much heat so mercury is best conductor of heat among the given options.
