Competency Group: Material Science
Description: Density measurement is a very important consideration when choosing a material as it gives direct indication about how much weight is involved for a particular size of device. Density = mass/volume. E.g. Density of water at 4deg Celsius is 1 Kg/Liter.
Citation for Description: Description by authors
Advantages: It is generally a known characteristic of any material and hence can be read directly off a data sheet.
Limitations: Not known what state a material is in — e.g. Mercury .
