प्रश्न
Halima picks up a small stone from the ground and puts it in the water in a dish. Does the shape of the stone change?

No, the shape of the stone will not change by putting it in a dish containing water because solids have definite shapes. They do not change their shape and retain it, no matter whatever be the circumstances.
