If Salt dissolves in water what does that mean? What does it mean that poppy seeds will float in water?

What does it mean that sand goes to the bottom in water?

Solubility of salt in water is due to bonds which can be formed between the 2, that is the water bonds will break the small bonds within the salt to form a big water-salt bond. Whereas the poppy seed,its made of stronger bonds water can't break and as its less dense than water,it just floats.

because salt dissolves in water that means that is a homogeneous substance, so is soluble.
Poppy seeds float in water because they are heterogeneous, and because is not soluble
and less dense than water.

When salt dissolves, the sodium and chloride ions are attracted to and ",ix in" witht he hydrogen and oxygen ions in the water. Since the ions are very small, we cannot see them and we call it dissolved.
Poppy seeds do not dissolve in water but stay seperate. Since they have a lower density than water, they float.

Poppy seeds are less dense than water so they float. I cant expalin the other one, sorry.
