Gas is not dense, solids should be dense, liquids are dense, but not as much as solids.
No. Several liquids, including gasoline, oil and alcohol, are less dense.
The atoms and molecules that make up stuff (gas, liquids, solids) make the stuff dense.
The more-dense liquid will sink because it's more dense and this is the lowest-energy state. If both are polar or both are nonpolar, some mixing will occur, but the effect can still be seen.
The 2 liquids are so dense that the two liquids will sit in top of each other without mixing
yes
In comparison to gases, yes; in comparison to solids, no.
Liquids can flow, their particles can move about more than solid particles, you can't compress them, and they are quite dense.
Gas is not dense, solids should be dense, liquids are dense, but not as much as solids.
All liquids are made up of matter (atoms and molecules) which is what gives them their densities. Liquids are dense because they are made up of matter so all liquids have the same ingredient to make them dense.
No. Several liquids, including gasoline, oil and alcohol, are less dense.
There are many liquids more dense than water. The most commonly thought of is probably Mercury.
Some liquids are denser than others. In general, everyday experience, most liquids are denser than gases, but not as dense as solids. There are some exceptions to this rule.
some solids are more dense than liquids (they sink) but others are less dense which is why not all solids sink
If an object or liquid is is less dense than the liquid in which it floats, that's the reason why it floats, because whatever is less dense floats. If you meant to ask why something MORE dense can float in something LESS dense, one answer is surface tension.
The intermolecular forces are weaker in liquids.
In general, solids are more dense than liquids which are more dense than gases.
