The surface of copper gets tarnished by the formation of copper oxide.
$N _2$ gas was passed to prevent the oxide formation during heating of copper at $1250 K$.
However, the $N _2$ gas contains $1$ mole $\%$ of water vapour as impurity.
The water vapour oxidises copper as per the reaction given below:$2 Cu ( s )+ H _2 O ( g ) \longrightarrow Cu _2 O ( s )+ H _2( g )$
$P _{ H _2}$ is the minimum partial pressure of $H _2$ (in bar) needed to prevent the oxidation at $1250 K$.
