We can place our hand inside water and move it freely , but cannot do it through wall. give reason.

Dear Student ,
Water has less density than the solid and due to this the we can freely move our hands in water but we can not move our hands in the wall .
Solid has more density than liquid water and the intermolecular attraction force is much more than the water , so we can easily displace water by our hand but can not move the walls .

Hope this helps you to clear your idea .
Regards
