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 else can I help you with?
Does a substance change mass if it changes physically?
No. Mass is a measure of how much matter is in an object, and that does not change when the matter changes states. The matter will either contract or expand, depending on the current state and the state to be reached, but that does not change how much matter is in the object.
What happens to density when it changes state?
When a substance changes state, its density can change. For example, when a substance transitions from a solid to a liquid state, its density usually decreases. Conversely, when a substance transitions from a gas to a liquid state, its density typically increases.
How is the density of a pure substance affected if the mass and or volume are changed?
The density of a pure substance remains constant regardless of changes in mass or volume. Density is a physical property that is inherent to a substance and is calculated as mass divided by volume. As long as the substance remains the same, the density will not change.
Is the specific gravity of substance the same when the substance is in the solid state?
No. Roughly speaking, "specific gravity" is equivalent to density, i.e., mass divided by volume. If a substance changes its state, its volume will change, but its mass won't change - therefore, the density - the result of the division - will also change.
Does a change in the mass affect the density of the object?
No, a change in mass alone does not affect the density of an object. Density is determined by the mass of the object and the volume it occupies, so changes in mass need to be accompanied by corresponding changes in volume to affect an object's density.
The density of a substance undergoes the greatest change when the substance changes from a?
from a solid to gas
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.
Does a substance change mass if it changes physically?

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.

How can you change density of a substance?
You can change the density of a substance by changing its volume. Density is equivalent to mass over volume. So changing the volume affects density.
Do characteristic properties change when sample changes?
Characteristic properties of a substance do not change when the sample changes. These properties, such as melting point, boiling point, density, and chemical reactivity, are inherent to the substance itself and remain constant regardless of the size or form of the sample.
What are two physical properties that can vary even when the substance with these properties dose not change?
Density and color can vary while the substance remains the same. Density is mass per unit volume, which can change depending on pressure or temperature. Color can vary due to factors such as lighting conditions or impurities in the substance.
What properties of a substance does not change when the amount of the substance changes 1 mass 2 volume 3 temperature?
The mass of a substance does not change when the amount of the substance changes. The temperature of a substance does not change when the amount of the substance changes. However, the volume of a substance may change when the amount of the substance changes, depending on the conditions.
What is physically happening when water is dissolving a substance?
when we dissolve a substance then first of all there may occur physical change like shape,colour,temperature etc. these changes are called physical changes.
