It's because no new substance is formed. It's the same substance just bigger or smaller.
Density and volume are two physical properties that can vary even when the substance does not change. The density of a substance can vary depending on the pressure and temperature, while the volume can change with the shape or container that holds the substance.
Volume is a physical quantity not a change. However CHANGE in volume is a physical change.
This is a physical change.
a physical change is a change in any physical property of a substance, not in the substance itself

A physical change. The chemical make up of the material is not changed. --------------------------------------------------------------------- Pressure is not a change, it is a characteristic. It is the ratio force/area.
Density and specific internal energy are two physical properties that change with temperaturea change in temperature.
a physical change will only alter the appearance but will NOT change the substance to another substance =)
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.
it would be physical change because physical change is when the substance stays the same
