Gas is compressible and the density changes significantly with changes in pressure.
The explanation may lie in density changes in blood plasma, the study said.
As the density changes, so does the index of refraction.
A newer type of stud finder works by detecting density changes in a wall.
The continuity equation describes how the density changes with time.
The material will always weigh the same, but the volume HAS to change if the density changes.
The density changes from 3.3 to 2.7 g/cm with a concurrent volume increase on the order of 30-40%.
Do not let the kids think the steel has a density change.
He added that the computer had actually asked him to tell it what the abnormal density changes were.
He said that the radar senses density changes underground and converts them into a picture.
