Answer 1

Answer:

1.Coating an iron sheet with a layer of zinc - GALVANIZATION

2.A solution in which no more solute can be disolved - it would be called as SATURATED

3.Why is iron covered with a layer of zinc? - It is done to prevent iron from rusting, as this stops oxygen and water to react with the metal underneath. Zinc is more reactive than iron, so it oxidises in preference to the iron object as a sacrificial metal.

4.Water changing into vapour - EVAPORATION

5.Why do ships rust more inspite of being painted? - Ships are made of iron and the lower part of them remains under water. the salt in the water makes the process of rust formation faster. Therefore, ships suffer a lot of damage from rusting in spite of being painted.

and your last question I can't quite get it.
