each substance has a density that differ from the densities of other substance.

What kind of changes in substances are always physical changes?
The kinds of changes in substances that are always physical changes are changes in the state. This is the change from solid, to liquid and then to gas and the reverse.
When matter changes state does become a different kind of substance?
Changes of state of matter are physical processes, the molecule remain unchanged.
What kind of change such as a change of state the substance of the whole changes but its underlying structure remains the same?
In changes in which the molecular structure of a substance remains constant, such as changes of state, we often refer to these changes as Physical Changes. If the molecular structure is altered it would be a Chemical Change.
Physical properties are altered but the substance remains the same kind of matter?
Physical properties are characteristics that can be observed or measured without changing the composition of the substance. When physical properties are altered, such as when a substance changes state (solid to liquid), the basic chemical composition remains the same, indicating that it is still the same kind of matter.
Melting freezing and boiling are what kind of change?
Melting, freezing, and boiling are physical changes, as they do not involve a change in the chemical composition of the substance.
What kind of changes is it chemical or physical and why?
a physical change is a phase change, such as water to ice or water vapor. a chemical change takes place on a molecular level, producing a new substance.
What kind of change happens when the composition of a substance does not change?
A physical change occurs when the composition of a substance does not change. This means the substance retains its chemical identity but may undergo a change in its physical properties like shape, size, or state of matter. Examples include melting, freezing, boiling, or dissolving.
What kind of change occurs with no new substance being formed?
physical changes
What kind of change happens when a substance dissolves?
I want to say physical change
What kind of properties can be determined without changing a substance into a different substance?
physical: color, shape, texture, smell, ext.
What is a change to a material that does not change its composition?
The kind of change described is referred to as a physical change. Examples of physical changes include, but are not limited to, changing the temperature or state of a substance, changing the shape of a substance, and breaking a substance into smaller pieces. A change that alters a material's composition would be classified as a chemical change.
What is a physical versus chemical change?
A PHYSICAL CHANGE MEANS CHANGE IN EXTERNAL APPEARANCE .A CHEMICAL CHANGE MEANS THE CHANGE IN THE PARTICLES BY WHICH IT IS MADE up OF.Physical Changes are d changes which are reversible .In this change we can get the products back. eg-Mixing of water and salt ,we can get salt back .Chemical changes are d changes which are irreversible . In this change we cannot get the products back . eg- Burning of candle , we cannot get the matchstick back after burning .
