are gases denser than liquids?

And the answer is yes. A gas can be more dense than a liquid. ... The density of a gas is directly proportional to the pressure and indirectly proportional to the temperature. This means that if the pressure increases, the density will increase and if the temperature decreases the density will increase.

Liquids and solids can be referred to as condensed phased because their particles are close together. Liquids and gases flow easily because their particles can move or slide past one another. Liquids and solids are not easily compressible; meaning they have little space between the particles.

['Low Density. Gases contain scattered molecules that are dispersed across a given volume and are therefore less dense than in their solid or liquid states. ... ', 'Indefinite Shape or Volume. Gases have no definite shape or volume. ... ', 'Compressibility and Expandability. ... ', 'Diffusivity. ... ', 'Pressure.']

The kinetic-molecular theory explains why gases are more compressible than either liquids or solids. Gases are compressible because most of the volume of a gas is composed of the large amounts of empty space between the gas particles.

Liquids have definite volume but gases do not have definite volume. Both liquids and gases do not have a definite shape and take the shape of the container in which they are stored. Liquids flow from higher level to lower level but gases flow in random direction.

Solids also have a high density, meaning that the particles are tightly packed together. In a liquid, the particles are more loosely packed than in a solid and are able to flow around each other, giving the liquid an indefinite shape. Therefore, the liquid will conform to the shape of its container.

The density of a pure liquid or solid is the same, regardless of how much pure liquid or solid is present. Only the concentrations of gases and substances in solution are included in the equilibrium expression.

Viscosity depends strongly on temperature. In liquids it usually decreases with increasing temperature, whereas in gases viscosity increases with increasing temperature.

Like liquids, gases have no definite shape, but unlike solids and liquids, gases have no definite volume either. The change from solid to liquid usually does not significantly change the volume of a substance.

Ice actually has a very different structure than liquid water, in that the molecules align themselves in a regular lattice rather than more randomly as in the liquid form. It happens that the lattice arrangement allows water molecules to be more spread out than in a liquid, and, thus, ice is less dense than water.

Salt water is more dense than fresh water That stuff would be the salt, which makes the mass of water greater, without adding much to its volume. Seawater is more dense than fresh water so it sinks beneath freshwater.

There are four natural states of matter: Solids, liquids, gases and plasma. ... Solids also have a high density, meaning that the particles are tightly packed together. Liquids. In a liquid, the particles are more loosely packed than in a solid and are able to flow around each other, giving the liquid an indefinite shape.

Gases, liquids and solids are all made up of atoms, molecules, and/or ions, but the behaviors of these particles differ in the three phases. ... gas are well separated with no regular arrangement. liquid are close together with no regular arrangement. solid are tightly packed, usually in a regular pattern.

Solid water, or ice, is less dense than liquid water. Ice is less dense than water because the orientation of hydrogen bonds causes molecules to push farther apart, which lowers the density. ... Because ice is less dense than water, it is able to float at the surface of water.

Gases have lower density than other states of matter, such as solids and liquids. ... When more gas particles enter a container, there is less space for the particles to spread out, and they become compressed. The particles exert more force on the interior volume of the container. This force is called pressure.

Because the particles in liquids are very close together (barely further apart than in solids) liquids do not easily compress, so their volume is fixed. Gases can also flow, so occupy the shape of their whole container. They do not have a fixed shape.

Summary. Gases will compress more easily that solids or liquids because here is so much space between the gas molecules.
