Why does magnesium react mildly with cold water but

Thus, the metal surface is dynamically dressed by hydrogen atoms and thereby screened from further attack by water.Hence, the reaction is mild in cold water. When the magnesium metal is exposed to hot water or steam, the temperature of the metal increases and its interatomic bonds loosen (destabilise) making the magnesium atoms to give away
