1. Energy density

   In physics, energy density is the amount of energy stored in a given system or region of space per unit volume. It is sometimes confused with energy per unit mass which is properly called specific energy or gravimetric energy density. Often only the useful or extractable energy is measured, which is to say that inaccessible energy (such as rest mass energy) is ignored. In cosmological and other general relativistic contexts, however, the energy densities considered are those that correspond to the elements of the stress–energy tensor and therefore do include mass energy as well as energy densities associated with pressure. Energy per unit volume has the same physical units as pressure and in many situations is synonymous. For example, the energy density of a magnetic field may be expressed as and behaves like a physical pressure. Likewise, the energy required to compress a gas to a certain volume may be determined by multiplying the difference between the gas pressure and the external pressure by the change in volume. A pressure gradient describes the potential to perform work on the surroundings by converting internal energy to work until equilibrium is reached.

1. Energy density

   Energy density is the amount of energy stored in a given system or region of space per unit volume or mass, though the latter is more accurately termed specific energy. Often only the useful or extractable energy is measured, which is to say that chemically inaccessible energy such as rest mass energy is ignored. Energy per unit volume has the same physical units as pressure, and in many circumstances is a synonym: for example, the energy density of a magnetic field may be expressed as a physical pressure, and the energy required to compress a compressed gas a little more may be determined by multiplying the difference between the gas pressure and the external pressure by the change in volume. In short, pressure is a measure of the enthalpy per unit volume of a system. A pressure gradient has a potential to perform work on the surroundings by converting enthalpy until equilibrium is reached.

Examples of energy density in a Sentence

1. Ken Boyce:

   It's not that the energy density going up makes it more dangerous, it just means that it's that much more important to make sure that safety is really holistically and very effectively managed.

2. Kevin Klatt:

   Oil is a really easy way to increase the energy density of a food. Things like almonds have a lot of fat, but it's easier to overeat pure oil than overeat pure almonds.

3. Dana Weigel:

   The exposed portion of the old arrays will still be generating power in parallel with the new arrays, but those new arrays have solar cells on them that are more efficient than our original cells, they have a higher energy density and together in combination may generate more power than what our original array, when it was new, did on its own.

4. Dana Weigel:

   The exposed portion of the old arrays will still be generating power in parallel with the new arrays, but those new Iris arrays have solar cells on them that are more efficient than our original cells, they have a higher energy density and together in combination may generate more power than what our original array, when it was new, did on its own.

5. Nour Makarem:

   There are number of mechanisms by which higher fiber intakes can contribute to successful aging, fiber is associated with increased satiety and fiber food sources typically have low energy density, thereby reducing the risk of weight gain, obesity and associated chronic disease.
