What else can I help you with?
When density increases the number of molecules in a volume increases decreases varies or stays the same?
When density increases, the number of molecules in a volume stays the same. Density is defined as mass per unit volume, so as the mass increases, there needs to be a proportional increase in the number of molecules to maintain the density.

What effect does an increase in pressure have on the density of a material?
An increase in pressure typically increases the density of a material. This is because the higher pressure causes the atoms or molecules in the material to be closer together, thus increasing the overall density.
What effects on density of air if tempecture increase?
A gas (including air) will expand if the temperature increases. That means the same mass of gas will have a larger volume. Since density is mass / volume, that means the density will decrease.
What happens to volume if density increases?
Density = mass / volume. Therefore, if volume increases and mass doesn't change, density will obviously decrease.
If density increases and mass stays the same then what happens to the volume?
the density increases
How are mass volume and density related to each other?
Density is defined as mass divided by volume. This means that density is directly proportional to mass and inversely proportional to volume. As mass increases, density also increases, while as volume increases, density decreases.
How is molecular mass and vapour density related?
density is mass per unit volume, meaning that as mass increases ,the density increases. Unlike volume, as it increases the density decreases.
What happens to the density as the volume increases?
If volume increases while mass remains the same, the density will decrease.
If mass stays the same and volume decreases what does density do?
Density increases
In gases. What happens to the density of a given mass if the volume increases?
If the volume of a gas increases, the density of the gas will decrease. This is because density is mass divided by volume, so as the volume increases while the mass stays constant, the density will decrease.
As a parcel of air increases in altitude its pressure will?
No, the density lowers. When air expands, the volume of area it takes up increases while the density decreases. The molecules move apart.
