Answer;

It becomes heavier.

- when a part rusts it becomes heavier due to addition of oxygen molecules.

Explanation;

-Rust is iron-oxide (hydrated iron (iii) oxide); a molecule consisting of iron and oxygen.

- When rust forms, the mass of the iron object is increased by the mass of oxygen that has combined with some of the iron and thus gains weight.

The answer to the question "When a part rusts is becomes heavier or lighter?" is the rust actually has a tendency to flake off. But as long as the rust is still on the nail, the nail will be heavier. The reason is that you are actually adding an oxygen and hydrogen to the nail.

Explanation:

The cellular process that enables the cells to grow and develop into tissue is mitosis.
