If solid H2O was more dense than the liquid form, ice (the solid form) would sink in water. In the freezing weather, ice would form, that ice would sink, and more ice would form. It wouldn't take long for a lake in a higher latitude to freeze solid. Additionally, it would never thaw out in the summer because the ice would be blanketed below a layer of water. The lake would become ice, and stay mostly that way before refreezing the next winter.
Usually a liquid, but some solids, like ice, have the molecules more spread apart, making it less dense than the liquid. If, by "loosely packed," you mean being able to slide past each other, then the liquid is always the answer.
what is the measure if how tightly matter is packed into a givin volume of a substance
The molecules in water are not tightly packed as such flow and spread very easily but when the water turns to ice the molecules in the liquid enlarge ans they tightly packed and thus, when water turns to ice new molecules are not formed.
rarefraction
In a solid, the molecules are packed tightly together in a fixed arrangement, maintaining a definite shape and volume. In a liquid, while the molecules are still close together, they have more freedom of movement and can flow past each other, causing liquids to take the shape of their container.
in solids molecules are tightly packed in liquid molecules are not so tightly packed whereas in gas they are free to move
Oil is a liquid . Because it has definite shape and volume.

(different ;)) the molecules are more tightly packed in a solid. an example of a sold is a TV an example of liquid is lemonaide
In a solid the molecules are tightly packed together all touching one another and vibrate; in a liquid the molecules are more loosely packed and more free to move around but they are still touching; in a gas the molecules are free to move where they please
density
Liquid molecules are very tightly packed while in gas it is loose.
At the molecular level, the main difference between a solid and a liquid is the arrangement and movement of molecules. In a solid, molecules are tightly packed together in a fixed position, vibrating in place. In a liquid, molecules are more loosely packed and can move around each other, allowing the liquid to flow.
Liquid molecules are very tightly packed while in gas it is loose.
The molecules present in the solids are tightly packed, while liquid has loosely packed molecules. Hence while meting solids they co-exist and show up as higher density than pure liquid.
When molecules are evenly distributed through a solid, liquid, or gas, we say that the substance is in equilibrium. In a solid, the molecules are tightly packed and vibrate in place. In a liquid or gas, the molecules move freely and randomly.
