What else can I help you with?
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 helium dense or less dense than water?
While the temperature and pressure a substance is under changes its density, it would take very high temperature and very low pressure on water and very low temperature and very high pressure on the hydrogen to make hydrogen more dense than water. So short answer, Hydrogen is less dense than water. While the temperature and pressure a substance is under changes its density, it would take very high temperature and very low pressure on water and very low temperature and very high pressure on the hydrogen to make hydrogen more dense than water. So short answer, Hydrogen is less dense than water.
Why the metal elements are hard?
have very high density and have high atomic mass
Does mercury have any density?
Yes, mercury does have a density. It is a dense, silvery liquid metal at room temperature with a density of about 13.6 grams per cubic centimeter.
How does the density of the sun vary from the center outward?
The density of the Sun gradually decreases as you move from the center outward. In the core of the Sun, where nuclear fusion occurs, the density is very high due to the intense pressure and temperature. As you move towards the surface, known as the photosphere, the density decreases as the material becomes less compressed.
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.

Can air pressure falls drastically at high altitude?
Air pressure falls of as one gains altitude. At high altitude the air pressure is very low but it does not "falls drastically", which implies a sudden change.
When graphite is subjected to very high temperature and pressure does it change to a diamond?
Graphite has its own atomic structure of its basic carbon atoms. Subjecting it to very high temperature and pressure would not change its structure. Carbon, when subjected to very high temperature and pressure can be crystallized into diamond structures.
Is it possible to have a very high systolic pressure and a very low diastolic pressure?
No.
Which two factors influence seawater density?
-As temperature increases, density increases (due to thermal expansion) -As salinity increases, density increases (due to the addition of more dissolved material) -As pressure increases, density increases (due to the compressive effects of pressure) of these 3 factors, only temperature and salinity influence the density of surface water. Pressure influences seawater density only when very high pressures are encountered, such as in deep ocean trenches.'' (Thurman H., et al, 2002)
High pressure gases?
when the collision between the gas molecules and the container in which the gas exist is very high.....then the pressure of the gas is very high
Will a hot air balloon fly better on high pressure or low pressure?
High pressure. A hot air balloon has a maximum altitude, where it has only just enough lift to keep it there, because there is very little difference in density between hot (near) vacuum and cold (near) vacuum.
Why the metal elements are hard?
have very high density and have high atomic mass
Does mercury have any density?
Yes, mercury does have a density. It is a dense, silvery liquid metal at room temperature with a density of about 13.6 grams per cubic centimeter.
When comparing gas and liquid the particles of liquid are closer together can liquids be compressed?
Yes, but very difficult: high pressure gives very tiny volume change
