The chemical reaction is:
Zn + 2 NaOH + 2 H2O = Na2Zn(OH)4 H2
Zinc can be virtually any temperature as can nearly all substances. No substance in inherently hot or cold.
Molten zinc refers to zinc metal that has been heated to its melting point, which is approximately 419°C (786°F). When zinc is in its molten state, it can be applied as a protective coating to other metals through processes like hot-dip galvanizing.
Zinc does react when heated. It sparks, then turns to a liquid. The reaction takes place because the zinc combines with the o2 and creates zinc oxide.
by cooling and then filtering
Steel is put in a pool of hot zinc at about 460˚ Celsius (860˚ Fahrenheit).

This is an exothermic reaction, which releases heat energy as the lye (NaOH) dissolves in water. This heat is generated due to the interaction between the ions in the NaOH and the water molecules.
Zinc reacts with steam to form Zinc oxide(yellow when hot and white when cold) and hydrogen. Zn+H2O=ZnO +H2
The chemical equation for sulfur reacting with hot concentrated nitric acid is: S + 6HNO3 → H2SO4 + 6NO2 + 2H2O

Lead sulfate can be dissolved in hot concentrated nitric acid or in hot concentrated sulfuric acid. It can also be dissolved in a mixture of hydrochloric acid and hydrogen peroxide. It is important to handle lead compounds with care due to their toxicity.

Hot dipped zinc is one common treatment, but there are others.
