Nothing, if it is the same amount of material in all three phases.
If however it is the same volume and pressure then solid and liquid phases will have about equal mass but the gas phase will have much less mass.
Solids are, well, solid, and have a definite shape. Liquids do not have a definite shape (but do have a definite volume), and neither do gasses (but they don't have a definite volume).
Solid matter is actually solid. Condensed matter is a liquid that is pressurized.
A solution can be a solid, liquid, & gas.
solid, liquid, and gases
Both gases and liquids have an indefinite shape - they will take the shape of the container they are held in. The difference between gases and liquids is that liquids have a definite volume while a gas does not.
What is the difference between solid and gas in terms of their fluidity
is there a chemical difference between the solid and liquid states of nitrogen
It is solid as it doesn't flow like a liquid or has vast space between its molecules like gases.
A solid and liquid have the same mass if the amount is the same.
Solids are, well, solid, and have a definite shape. Liquids do not have a definite shape (but do have a definite volume), and neither do gasses (but they don't have a definite volume).
temperature
There is plenty of space between the molecules of a gas but relatively little between those of a solid or liquid.
the only difference is the energy of the atoms
The atoms in a solid are in a tighter formation that as they are in a liquid. In a liquid, They are loose and have the ability to pour.
The molecules in a solid vibrate in place. The molecules of a liquid are moving about.
Urine is liquid Feces are solid
