Yes, we now know that the density of ice is less than that of water. Ice takes up more space than water for a given weight. In fact the density of ice is 7.65 pounds/gallon compared to 8.35 pounds/gallon for water. Therefore, one gallon of ice weighs 7.65 pounds, but 7.65 pounds of water is only 7.65/8.35 = 0.92 gallons of water.
Gas also changes but as the tempature changes so does 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.
Is Density is a property?
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.YES.
Is density a physical change or chemical?
A change in density may accompany a Physical change. When liquid water becomes solid water, the solid water FLOATS; (is less dense) on top of its liquid form.Density itself is a physical property, not a change.
Is the density of a substance a physical property of the substance?
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.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
Is density a physical or chemical change or is it a physical and chemical change?
Your answer will be physical property.It can also be physical change when you're telling the density of an object. And the reason why is "density" is... physical is just those kind of stuff...
How is an chemical change differs from a physical change?
Physical change is the change in which only physical properties changes ,like color, hardness, density etc. Chemical changes affect the composition as well as chemical properties of matter and result in formation of new substance. Examples of chemical changes are : Burning of coal Burning of Paper Electrolysis of water
If water is boiling is it a chemical change or a physical change?
It is a physical change. All phase changes are physical, not chemical. The chemical composition of water does not change when it changes from a liquid to a gas, or for that matter, to a solid.
When water changes phase is it chemical or physical?
Physical, as it remains water.
What is the density of 300 milliliters of water with 108 milliliters of water?
The density of water does not change when the volume changes. This is because density is a proportion of weight to volume. The density of water changes with temperature, but is approximately 1g/ml.
Is water turning to snow a chemical or physical change?
Changes of state are physical changes.
8 Does the density of water change as it mass changes?
No way!
