This is not entirely true. The mass will only increase with volume if you are adding more to to increase the volume. However, you can increase the volume without increasing mass. An example of this would be heating something. As you heat things the molecules want to move about more, as this happens they spread further and further apart. This is easiest to observe in when things are in a gaseous state. You can determine how the volume of a gas changes by PV=nRT; where P is pressure, V is volume, n is he number particles, R is constant, and T is the temperature in Kelvin.

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 changes when the mass of an object increases while volume stays the same?
Assuming mass does not also increase, then density decreases if volume increases. For example, let's say Mass= 100 and Volume= 50 Density would = 2 Now, lets increase the volume. Mass would still = 100, and let's increase the volume to 75. Density would then equal 1.333... 2 is greater than 1.333.... so yes, density decreases as volume increases.
When temperature increases does density increase or decrease?
An increase in temperature usually causes an increase in volume. Since the mass doesn't change, density decreases. tt
What happens if the density increases?
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.
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.
Can a increase in density result from an increase in mass and no change in volume?
Yes. Density is mass/volume so if mass increases so does density if volume does not change
What happens the mass of an object increases but the volume stays the same?
at constant temperature in a closedcontainer the increase in temperature increases the volume of a gas but not the mass.
If the volume of an object increases what will the density do?
it will increase. the epuation for density is mass divided by volume.
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)
Why does the density of water increase when salt is added to it?
Density = Mass/Volume As salt(mass) increases and the volume remains the same, density also increases.
Why alkali metal density increase going down the group?
Atomic-volume of alkali metals increases down the group ,But increase in mass dominates over increase in volume ,since density=(mass)/(volume) ,density increases down the group
What changes when the mass of an object increases while volume stays the same?
Assuming mass does not also increase, then density decreases if volume increases. For example, let's say Mass= 100 and Volume= 50 Density would = 2 Now, lets increase the volume. Mass would still = 100, and let's increase the volume to 75. Density would then equal 1.333... 2 is greater than 1.333.... so yes, density decreases as volume increases.
What happens to the density of an object if the mass increases but the volume stays the same?
If the volume remains the same, the density will increase in direct proportion to the increase in mass.
What changes when the mass of an object increases while the volume stays the same?
Well, the density definitely increase because it is the mass/volume.
What happens to density if the volume increase?
must decrease
Why temperature increases dencity decreases?
Density is mass divided by volume. For most substances, when the temperature increases the volume will increase (assuming constant pressure), but the mass will of course remain unaffected.
Will density decrease or increase if mass stays same but volume increases?
density decreases
