"جامدات" refers to solids, one of the three primary states of matter, alongside liquids and gases. Solids have a definite shape and volume, meaning they do not change form easily. The particles in solids are closely packed together, which allows them to maintain their structure and resist compression. Examples of جامدات include everyday materials like الخشب (wood), المعادن (metals), and الزجاج (glass). These substances can be found in various applications, from construction to household items. Understanding جامدات is essential in fields like الفيزياء (physics) and الكيمياء (chemistry), where the properties of materials are studied.
