I couldn't think of any simpler way to help without directly giving the answer.

$H_2O~+~\color{red}{heat}$ <=> $H^+ + OH^-$

at $25^o$ C pH + pOH is 14

if you heat it further the reaction goes in the forward direction and more ions are produced

$k_w = [H^+][OH^-]$
$pK_w = pH + pOH$
more the ions more the $k_w$  less the $pK_w$
