Answer 2

Things become weak due to many factors-

1. Corrosion - corrosion is the degradation of a metallic substance as a result of chemical reactions between it and the components in the surrounding environment. Examples - rusting of iron and due to corrosion the metallic materials lose their strength and become brittle.
2. weak intermolecular forces of attraction -Objects can also become weak due to weak intermolecular forces of attraction between them. The lower the intermolecular forces of attraction the weaker the particles become.
