For most materials and substances, and not allowing other parameters to change (like temperature), the density goes up as pressure increases.
One way to look at is like this:
Suppose a balloon is filled with air -- and sealed. Dunk it under water, which squeezes it harder, thus decreasing the volume.
The total mass is the same.
Density = mass / volume.
Since volume has gone down, density has gone up.
Another way.
Put more air in the balloon, but instead of a balloon, it has a rigid inflexible wall. Now the volume has not changed, but the mass is higher (since you increased the amount of air).
So the density is higher (see above).
But what happened to the rigid walls of the balloon. The air pushes harder on them!
So increased density causes higher pressure, and higher pressure causes increased density.

How does increasing the density of a gas affect the pressure?
By increasing the density of a gas its air pressure will subsequently increase.
Does density increase decrease or stay the same if temp and mass of a liquid increase?
Depends on the other conditions. If the volume remains constant, the density will remain the same (but the pressure will increase). If the pressure remains constant, the volume will increase - and therefore the density (mass / volume) will decrease.
What is the reduction in the density of a medium?
It is the result of a decrease in the pressure or an increase in the temperature of a medium.
What is a result to increasing the temperature of a gas?
In a closed system the pressure increase. In other conditions the volume increase and the density decrease.
Why is density of water more in deep water?
The density of water increases with depth due to the increase in pressure. As water molecules are packed closer together under high pressure, the density of water increases. Therefore, in deep water where the pressure is higher, the density of water is also higher.
How does the density of the air affect pressure?
Pressure affects the density of air by increase of pressure increases the density
How does increasing the density of a gas affect the pressure?
By increasing the density of a gas its air pressure will subsequently increase.
How does increasing the density of gas affect its pressure?
By increasing the density of a gas its air pressure will subsequently increase.
Does the air increase or decrease towards the surface with a high pressure?
Air density and pressure increase nearer the surface
If you add pressure to an object what happens to its density?
the density will increase because there will be less space
What effect does an increase in pressure have on the density of a material?
When pressure increases the volume of the material decreases. Density=mass/volume When volume decreases density increases.(Mass constant)
What happens when pressure is increased on gases?
The volume decrease and the density increase.
How does increasing the density of a gas causes the pressure to increase?
The obvious answer is that the more there is the more there is. More molecules more density, more pressure inside the vessel.
What effect does air density have on the absorption and radiation of energy?
An increase in air density will mean a decrease in the absorption and radiation of energy. An increase of air density causes temperature and pressure to rise.
Does density increase decrease or stay the same if temp and mass of a liquid increase?
Depends on the other conditions. If the volume remains constant, the density will remain the same (but the pressure will increase). If the pressure remains constant, the volume will increase - and therefore the density (mass / volume) will decrease.
How is it that the altitude decrease and the density of the air does what?
Altitude decreases, pressure increase, temperature decreases (some, but less effect than pressure), density goes up.
How does the pressure exerted by a liquid change as density of the liquid changes?
In general, yes. For a simple situation of a constant gravitational force, the equation is P=rho*g*h. where rho = density, g = 9.8ms^-2, h corresponds to depth.
