The only way that the mass can change is if matter is added or taken away. The volume of a liquid can increase if heated, such as the liquid inside of a thermometer. The thermometer is sealed and no liquid gets in or out, so the mass of the liquid is unchanged. But when the temperature goes up, the liquid expands and is forced to go up the thermometer.

If mass or volume is changed, the density (mass per volume) will also change.

No, the mass and volume stay the same but the shape changes. Changes in state never change it's mass but if it changes to gas, the volume is unmeasurable.

mass stays the same, however volume changes. If it is going from solid to liquid or liquid to gas, the volume increases. If it is going the opposite direction, then volume decreases. An exception is water, which increases in volume as it goes from liquid to solid.

Because when the volume of an object,liquid,or gas Exspand then the density changes Mass/Volume= Density

That change is known to be a change of state. Gas becomes liquid. If gas is taken out we can change the volume at constant temperature and pressure conditions. That is mass changes hence volume changes keeping the density constant.

The mass doesn't change in this case. Only the volume changes.

The mass of a liquid and the volume of it are not related, they have no bearing on one another. The mass and volume can change independently, in theory. They are related by the equation to calculate density. Density=Mass/Volume

Mass -- won't change Volume -- will increase (for most liquids, over most temperature changes) Density -- will decrease (for most liquids, over most temperature changes).

No, cooling a liquid will not make it lighter.

Yes under constant pressure, with a given mass, volume changes during the change of state. When steam condenses, its volume is reduced. But, when water changes into ice, its volume becomes more. This is known to be anomalous expansion of water. Where as in other cases, when the liquid form gets changed into solid form, the volume is reduced.

Quantities which depend on the mass of an object are its momentum, and kinetic energy.Both change if the mass changes. In addition, if the object's volume doesn't change,then its density also changes.

Density = mass / volume. So if the volume changes, the density will obviously also change.

Mass is conserved. Volume changes slightly, so density changes as well, but mass remains the same.

If you know the density and mass of the liquid, you can calculate the volume by dividing the mass by the density. density = mass/volume volume = mass/density mass = density X volume

A phase change does not result in a mass change. The density of a substance may change, but the mass will not. If a kilogram of water changes phase into ice, there will be a kilogram of ice. The volume of the ice will be greater than the volume of the water, but one kilogram is one kilogram.

Recall the formula for density. D = M/V. As V the volume is said to be constant then density D is directly proportional to the mass. Hence as there is a change in mass then density also changes accordingly

Yes it does change because its mass does not change but its volume does. When it is compressed the density will increase because its volume does. When it is attenuated will decrease because the volume does. Density is mass over volume. Remember: it only works because its mass stays the same and the volume changes.

Yes. In terms of chemistry, when a liquid becomes a gas the volume of the gas is equal to the container volume while the mass of the gas does not change. Mass will never change unless more moles are added.

When a liquid changes to a gas, the space between its molecules increases substantially, so the same amount of mass occupies a much larger volume.

The mass is the same. However the volume changes. The water is the most dense at 3.98 degrees C.

The mass of a liquid (or anything else) divided by the volume is defined to be its density.
