In gases. What happens to the density of a given mass if the volume increases?
it decreases.
How is volume and density affected when the temperature is decreased?
In general when temperature is decreased the volume decreases and the density increases. This is not true for water around freezingg temperatures, the volume increases and the density decreases and ice floats.
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
How is density related to the states of matter?
Solids have the highest density, followed by liquids and then gases.
An increase in density can result from?
Density (notably for gases) is increased by adding matter to a fixed volume (gases) or by reducing the volume in which it is contained (increases pressure). Solids and liquids are not actually compressible, but vary in density according to the molecular arrangement. Generally, the lower the temperature is, the lower the volume would be (volume is the amount of space an object takes up) because the atoms in an object will compact together when they have less energy. If the temperature is low, the volume will be low, and DENSITY INCREASES. If a substance has weak bonds that connect its atoms together, the volume will be higher because atoms are more spread out when it is a weak bond.
In gases. What happens to the density of a given mass if the volume increases?
it decreases.
What happened with density of gases on heating?
As gases are heated up, its volume increases, resulting in a decrease of density.
What happens when particles are of matter are forced closely together?
The substance would occupy less space. This is only possible with gases. Density increases (with solids, liquids, and especially gases)
What happens to volume if a material is placed under pressure?
The density increases. A lot for well-compressible substances such as gases, a little for hardly-compressible substances such as water.
How does oxygen content change with altitude?
The density of air decreases with altitude, so the ratio of oxygen in the air stays the same, but the amount of gases in your lungs decrease.
What happens to the density of solids liquids and gases when they are heated?
they are compromised.
What happens to pressure if temperature?
Are you referring to gases?In gases,if the temperature increases then the pressure would also increase.
What happens when pressure is increased on gases?
The volume decrease and the density increase.
If temperature increase what happens to pressure?
Are you referring to gases?In gases,if the temperature increases then the pressure would also increase.
What is the heaviest elemet of the noble gases?
Down the group the density generally increases. Thus radon will be the heaviest element.
The Uppermost atmospheric layer?
The uppermost atmospheric layer is the THERMOSPHERE. here temperature again increases with altitude because many of the gases are absorbing solar radiation.
The solubility of gases do what as temperature increases?
The solubility of gases decrease as temperature increases.
