Answer:

Grains of rice and rice flour are considered solids, despite appearing to take the shape of their container. This is because:

1. Each grain or particle has its own fixed shape and volume.
2. When poured into a jar, the particles slide and settle, filling the space-like sand.
3. They don't flow like liquids and don't merge into one continuous substance.
4. So, they behave like solids in bulk, but because they're made of tiny pieces, they can look like they're flowing.
5. It's a bit like a crowd of people-each person is solid, but the group can move and change shape.
