Silver is the best conductor of heat .
Heat
Heat is a form of energy that flows between a body and its surrounding medium by virtue of temperature difference between them.
The degree of hotness of the body is quantitatively represented by temperature.
S.I. unit of heat is Joule (J).
Heat can be transferred from one medium to other by the following three ways-

Which of the following is the best conductor of heat?a)Mercuryb)Silver...
Explanation:
Heat conduction refers to the transfer of heat energy through a material. The rate at which heat is conducted through a material depends on its thermal conductivity, with higher thermal conductivity indicating a better conductor of heat.
Silver:
- Silver is known to have one of the highest thermal conductivities among all metals.
- It has a thermal conductivity of approximately 429 W/mK, which makes it an excellent conductor of heat.
- Due to its high thermal conductivity, silver is commonly used in various applications where efficient heat conduction is required, such as in electronics and thermal management systems.
In comparison to other materials listed:
- Mercury has a much lower thermal conductivity than silver.
- Copper has a high thermal conductivity as well, but silver surpasses it in this aspect.
- Iron has a lower thermal conductivity compared to silver.
Therefore, among the options provided, silver is the best conductor of heat due to its high thermal conductivity, making it an ideal choice for applications requiring efficient heat transfer.
