Question

iron ball is a solid ball and water is a liquid . how do the two differ with respect to their shape ,size,diffusion and density?

Answer 1

The solid iron ball and water have the following difference:

The iron ball being solid has very tightly packed atoms that are strongly bonded as compared to the water. This would lead to the following difference, in terms of their;

1)shape- the shape of the iron ball is fixed. The only way to change the shape of that iron ball, is if it was to be molten and given another shape. On the contrary, water takes the shape of the container it is put in.

2)Size:
The same amount of atoms of iron would occupy a smaller space as compared to the same amount of atoms of water. This therefore means that for the same amount of atoms of iron compared to water, the iron will be smaller in size.

3)Diffusion:
Diffusion in water is possible but very slow, liquids are able to diffuse as their particles can move around each other. Solids on the other hand, like this iron ball, do not diffuse as the particles constituting it are not free to move around.
4)Density:
Density refers to the mass of an element per unit volume. Since the particles of the solid are tightly packed together, its mass per unit volume will be higher than that of water.

Answer 2

First answer is right.....
