Sodium responds viciously with chilly water. This is on account of it is high in the reactivity arrangement. On account of sodium and potassium, the response is so fierce and exothermic, that advanced hydrogen instantly bursts into flames. Iron doesn't respond with water, however, responds with a stream of delayed presentation.
It is the unique property of sodium and iron that sodium responds enthusiastically with water for which is put away in kerosene and iron and different metals like Aluminum doesn't respond with hot or icy water, however, responds with the stream.

In GENERAL, "Metals react with water to form Metal hydroxide or Metal Oxide AND Hydrogen Gas "
METAL + WATER ---->METAL HYDROXIDE/ METAL OXIDE +H2
Exceptions :
All the metals ,however will not react with water. The intensity of reaction of metal with water depends upon its chemical reactivity.
1. Case Of Sodium :
Sodium being very reactive reacts vigorously with cold water which results with release of lot of heat along with flames.
2Na(s) +2H2O(l)----->2 NaOH (aq) + H2(gas ) + heat.
As the reaction is highly exothermic , the hydrogen gas produced in this reaction catches fire and burns causing little explosion.
2. In case of Iron:
Iron is very less reactive compared to sodium, hence it cannot react with cold water .
But Red-Hot Iron reacts with steam to form IRON[II,III] oxide and hydrogen.
3Fe (S) + ---> 4H2O(g) ---> Fe3O4(s) +4H2(g)
