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

$Ag$ 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.
