Is the density of liquids the same as the density of gases?
No, it isn't.
Do you need great pressure change to have a measurable change density in gases?
Density = mass / volume, so to change density you need to change the mass within a fixed volume or the volume of a fixed mass. Increasing the mass or decreasing the volume will increase the pressure by a linear degree, so no, the density of a gas is very easy to change. E.G.: Decreasing the volume by 1.0% will increase the density by 1.1%. Increasing the mass by 1.0% will increase the density by 1.0%.
Is true about density and states of matter for most substances?
The density of solid state of matter is higher than the density of liquids and the density of liquids is higher than the density of gases.

What is the trend in density in noble gases?
The densities of the noble gases increase with increasing molecular mass. The increase in density is due to the increase in atomic mass. Helium is about one seventh the density of air and can be used in balloons and lighter-than-air craft. Xenon is about five times the density of air.
How does density change?
Density usually changes when an object is heated or cooled - especially in the case of gases, or when there is a change of phase.
How can you change the density?
Gases can change their volume and that causes the density to change. Liquids and solids are practically incompressible. Their volume change under pressure is such a small amount that their density changes very little if at all.
How can pressure change the density of solids liquids and gases?
Pressure can change the volume of all three (to varying degrees) and density = mass (which doesn't change) divided by volume.
Is the density of liquids the same as the density of gases?
No, it isn't.
What happened with density of gases on heating?
As gases are heated up, its volume increases, resulting in a decrease of density.

Is temperature a factor in determining density?
In the case of gases yes. For a gas, the density is directly proportional to the pressure and inversely proportional to the temperature (absolute ie Kelvin). In other words the higher the temperature the lower the density. This is because gases expand with temperature. Liquids and solids do expand but only slightly so there is not much change in density for these.
Is the density of gases a characteristic property?
The density is a physical characteristic, specific for each material, including gases.
Why does a gas not have density?
All materials - including gases - have a density !
Which phase has the lowest density when comparing solids liquids and gases?
Gases
What has low density?
Gases, for example
Why do solids have the highest density and gases have a lower density?
Solids tend to have a higher density because the molecules are arranged closer together where as in gases the molecules are further apart. Since density is Mass/Volume, and solids have more mass per volume than gases it is more dense
