Detailed Solution

The above statement is true.
Under normal conditions, aluminium does not react with water due to the presence of a thin layer of aluminium oxide on its surface. Under normal circumstances, aluminium does not react with water because other entities interfere with the chemical reaction and alter the results. The reaction of aluminium with steam is:
2Al (s)  +  3H2O (g)  → Al2O3 (s)  +  3H2 (g)
