And one way to measure the amount of sugar in a solution is to determine its density (the
mass per unit of volume).
The company also claims the inverter's compact design allows for an «unprecedented degree» of power density, which refers to the amount of energy that can be
transformed per unit of volume.
Let's start with osteoporosis which is defined as «the reduction in mass of
bone per unit of volume, interfering with the mechanical support function of bone.»
ii) In the case of the Ideal Gas Law it is the height of an atmosphere of a given mass that determines the number of molecules
per unit of volume at the surface and the more molecules per unit of volume the hotter the surface will become at a given level of solar input.
