Question

Priya has to choose between silver and copper vessels for heating. You would suggest Priya to prefer:

• A. a copper vessel because it is a better conductor of heat than silver
• B. a copper vessel because it is not a conductor of electricity but a good conductor of heat
• C. a silver vessel because it is a better conductor of heat than copper
• D. none of these because they are non-conductor of heat

Answer 1

Answer: (C)

a silver vessel because it is a better conductor of heat than copper

$Ag$ is better conductor than $Cu$ as $e^{-}$ can move freely. Also $Ag$ has single valence $e^{-}$ experiencing least electronic pull by the nucleus due to its number of protons and its atomic radius.
