As the density of a substance increases the volume of a given mass of the substance decreases.
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.
Decreases
E=mc2
As the air bubble increases in volume, its mass remains constant. Because the mass remains constant but volume increases, density will decrease.
The answer depends on what happens to other characteristics: particularly density or volume
it decreases.
In almost all cases, the matter expands. Density = mass / volume. When volume increases, the density decreases, because the mass is fixed.
If your mass increases, your weight also increases.
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.
As the air bubble increases in volume, its mass remains constant. Because the mass remains constant but volume increases, density will decrease.
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 answer depends on what happens to other characteristics: particularly density or volume
it decreases.
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.
