Question

Sand takes shape of any container but still it is a solid.how?

Answer 1

1. Sand appears to take the shape of the container, but in actuality it really does not.
2. There is enough space between the particles of sand, that it will not completely occupy the volume/space of the container.
3. The reason it appears to do so, and it appears to flow like water, is because even though sand is a solid, it is considered to be what is called granular.
4. Granular solids are made up of very small solid particles.
5. The space between these particles is greater than that in a regular solid, and this is what allows it to look like it flows and takes the shape of the container.

Answer 2

because there is a lot of space between the particles of sand
