As the density of a substance increases the volume of a given mass of the substance decreases.
When volume increases and mass remains constant, density decreases. This means that the same amount of mass is spread over a larger area or space. However, if mass is added while volume increases, density may remain constant or increase, depending on the rate of mass increase compared to volume increase.
If the pressure remains the same, the volume will increase.
Additional answer
Not always. Solids don't change in volume very much, and in fact water contracts when you heat it from 0 degrees to 4 degrees centigrade.
No. An increase in volume decreases its density. This will occur when a substance is heated.
Density is directly proportional to Mass. When mass in increased, density also increases.
i.e.Density = Mass/Volume
If there is no increase in mass the density will decrease.
? Thermal expansion ?
The density is lower.

The answer depends on what happens to other characteristics: particularly density or volume
it decreases.
The mass of the air bubbles remains the same as they rise in water, but their density decreases. This is because as the volume of the air bubbles increases, they displace more water, causing their density to decrease relative to the surrounding water.
In almost all cases, the matter expands. Density = mass / volume. When volume increases, the density decreases, because the mass is fixed.
If the mass of an object increases while the volume stays the same, the object becomes denser. Density is a measure of how much mass is contained in a given volume, so as mass increases without a change in volume, density increases accordingly.
Density = mass / volume. Therefore, if volume increases and mass doesn't change, density will obviously decrease.
the density increases
at constant temperature in a closedcontainer the increase in temperature increases the volume of a gas but not the mass.
If volume increases while mass remains the same, the density will decrease.
The mass of the air bubbles remains the same as they rise in water, but their density decreases. This is because as the volume of the air bubbles increases, they displace more water, causing their density to decrease relative to the surrounding water.
When mass increases and volume stays constant, the density increases. When volume increases and mass stays constant the density decreases. When they both change, then the density will depend on the rate of change of mass and the rate of change of volume.

The mass either decreases or increases
must decrease
Density is a characteristic of a given material. Water, for example, has a certain density (which is somewhat dependent upon temperature but let's say that the temperature is constant). It does not matter how much water you have, it will all have the same density. One teaspoon has much less mass, but the same density as an entire ocean.
If the volume remains the same, the density will increase in direct proportion to the increase in mass.
