What else can I help you with?
Can you change the density of substances?
yes.
Does a substance change density if it changes physically?
Depends on what you consider a physical change. Substances change their density when they change their state of matter. When the temperature rises, substances usually expand, wich leads to the density decreasing. When the temperature falls, substances contract, increasing the density. Exception would be water, as it shows an anomaly occurring near 273K
What is the only way the density of a pure substance can change?
The density of a pure substance can change by altering its temperature. As temperature increases, most substances expand and therefore decrease in density, whereas as temperature decreases, most substances contract and increase in density.
How will the density change if the temperature increased to 125?
If the temperature increased to 125 degrees Celsius, the density of most substances would decrease. This is because as temperature goes up, the particles in the substance gain more kinetic energy and move farther apart, decreasing the density.
Why is dencity a physical change?
Density is classified as a physical property because the density of a substance can change when the substance changes state. Example: When water evaporates it is a physical change and the density changes. A chemical property is a property that describes its ability to react chemically with other substances and THEREFORE density is not a chemical property.
Density of an object is less than density of water?
It is for some substances and not for other substances.
Is Density is a property?

Will the density of gold ever change?
No density of a object (mostly solids) never change not even when gold is in a ring or a necklace. Because in my science book it states "Density is a physical property of a substance. Density is the same for a substance no matter how much it is measured"
If 2 pure substances have the same density are they same substance?
Not necessarily. Two pure substances can have the same density but still be different substances. Density is an intensive property that is dependent on the substance's mass and volume, not its chemical composition.
How does density react in earth?
The word 'react' in chemistry means the interaction of substances to form new substances. It has nothing to do with density. Density is measured for a substance that is NOT undergoing a reaction.
Why does the density of a substance remain the same for different amount of the substances?
Density represents mass per volume and so when homogeneous (and incompressible), an amount increase/decrease does not change density, as the mass and volume change in the same proportioning. Water density is 8.34#/cu ft, whether it is 2 cubic feet or 4 cubic feet.
Does water have a high density compared to other substances?
Yes, water has a relatively high density compared to many other substances.
