Question

Why do solid have A definite volume?

Answer 1

Gases & liquids can flow & take up the shape of their container because they have weak intermolecular forces between them & the ion are not arranged in a regular method. As a result, when certain pressure or temperature is applied to them,their ions or molecules rearranges themselves & show flow properties. But in case of solids, the ions or molecules are arranged in a regular & repeated three dimensional pattern. So, whenever pressure or heat is applied to solids ,their ions or molecules do not rearranges themselves, and hence do not show flow properties & have a definite volume.

Answer 2

because solids have particles pass pass...
particles pass hote ...
they cannot rotate easily...
like liquid and gases...
because they have tightly bounded with bonds
intermolecular forces...so they cannot rotate..
so they have fixed volume and shape
