Question

since we can pour sand into a cup why isn't it a liquid

Answer 1

Sand crystals has definite shape and size it is not called as liquid

Answer 2

It isn't liquid as each grain has a shape and is solid.

• Sand is a grainy substance that is composed of tiny mineral fragments.
• It is a solid that may be poured like a liquid and mould itself to the proper shape of the standard container in which it is typically placed.
• Sand is, nevertheless, a solid because each grain of sand possesses a distinct form that it maintains.
• Because each grain in active substances like sand, salt, and sugar retains its unique structure when they are poured from a container, they will build up on the floor or a tabletop.
• Since they naturally have no complex structure, liquids cannot typically form a pile when they are poured over the same surface.
