Name any one metal which reacts neither with cold water nor with hot water but reacts with heated steam to produce hydrogen gas.
(IRON) Iron $(Fe)$,aluminium $(Al)$,and zinc $(Zn)$ do not react with either cold or hot water. They react with steam to form metal oxide and hydrogen gas. For example,the reaction of iron with steam is:
$3Fe(s) + 4H_2O(g) \longrightarrow Fe_3O_4(s) + 4H_2(g)$
$3Fe(s) + 4H_2O(g) \longrightarrow Fe_3O_4(s) + 4H_2(g)$
