Density usually changes when an object is heated or cooled - especially in the case of gases, or when there is a change of phase.
Pressure Temperature Changes in the molecular structure(chemical change)
Typically two dozen cookies equal one pound. This number changes with the size and density of the cookies being weighed.
Graphs show the relationship of one quantity to another. For example, it may show how the density of a material changes when the temperature is increased, or it may show the inflation depending on time. Vertically you show the quantity of interest (density, inflation) and horizontally what it depends on (temperature, time). You measure / look up / guess for each temperature the density, and draw a dot which is above the given temperature and to the right of the given density, and you do that for many densities.
The change in density of a fluid can be neglected if the temperature change in it is small. This assumption is however not applicable when buoyant forces are in consideration as gravity changes the specific weight of a fluid considerably.
density changes when the substance changes.
Color and density are physical properties, not changes.
The density changes.
by density change
Density never changes >.<
The density changes in direct proportion with the mass. A lesser mass results in a lesser density and a greater mass results in a greater density.
yes it does
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.
density changes as the altitude changes.
Density of R-134a changes with respect to temperature and pressure.
