Cryogenic tanks are never completely filled, to prevent severe pressure drop in the tank after engine start. On the ground, or in the continued gravitational field of Earth during rocket-propelled ascent, the space between the top of the propellant load and the top of the tank is known as "ullage space".

The harmonic capacity can also be understood as a limit of the condenser capacity. To wit, let S r denote the sphere of radius r about the origin in . Since K is bounded, for sufficiently large r, S r will enclose K and (Σ, S r) will form a condenser pair. The harmonic capacity is then the limit as r tends to infinity:
For example, the 1s subshell is filled before the 2s subshell is occupied. In this way, the electrons of an atom or ion form the most stable electron configuration possible. An example is the configuration 1s 2 2s 2 2p 6 3s 2 3p 3 for the phosphorus atom, meaning that the 1s subshell has 2 electrons, the 2s subshell has 2 electrons, the 2p ...
For example, heat capacity is an extensive property of a system. Dividing heat capacity, , by the mass of the system gives the specific heat capacity, , which is an intensive property. When the extensive property is represented by an upper-case letter, the symbol for the corresponding intensive property is usually represented by a lower-case ...

The proportion of space filled by the spheres is called the packing density of the arrangement. As the local density of a packing in an infinite space can vary depending on the volume over which it is measured, the problem is usually to maximise the average or asymptotic density, measured over a large enough volume.
