Metals react with water to form oxides or hydroxides and release Hydrogen gas. To me, it seems like a metal would need to be more reactive to be able to react with hot water since HCl is a very strong acid and so should theoretically be able to react with more metals, but I am not so sure. In general, the more reactive the metal, the more rapid the reaction. Can 1 kilogram of radioactive material with half life of 5 years just decay in the next minute? Zn,Al,Fe react with water to form metal oxide. 2)Magnesium is less reactive metal so it react slowly with cold water,it reacts rapidly only with hot boiling water. The reason for using cold water rather than hot water for the reactions of alkali metals is that alkali metals are already reactive enough at room temperature. Metals which react with steam form the solid metal oxide and hydrogen gas. 1)Sodium is a very reactive metal,therefore sodium metal react violently even with cold water.
