A change in volume with a constant, unchanging Pressure and Temperature results in increased or decreased density, inversely dependent on increase or decrease in volume.
Typically, a lower temperature denotes higher density, but many LIQUIDS are uncompressible (water actually expands slightly as it freezes) and therefore density in maintained. FLUIDS on the other hand encompass both liquids and gasses, of which gasses ARE compressible and will increase in density as temperature drops.
The intermolecular strength is higher in liquids than in gases.
Liquids and gases can change shape without any change in weight.
Not all liquids have lower densities than all solids. Low density solids frequently contain air or other gasses as part of their makeup (cok, Styrofoam, etc)
The higher the density, the faster the sound. Solids, then liquids, then gasses.
Liquids yes, gasses yes, solids no
ANSWER unlike solids, both liquids and gases can change their shape to fit the container in which they are held. however, gases can also change volume unlike liquids.
it becomes thinner. mass can't be created or destroyed, it only encompasses solids , liquids, and gasses.
molecules move more in gasses gasses>liquids>solids
Liquids and gasses tend to expand when heated, this lowers the density, thus warm "air" rises and cool air falls.
gasses
yes
