An important conclusion is that the temperature dependence of latent heat must be taken into account. We also demonstrate that the zero-point energies of various species do not affect the moist static …

Einstein and the conservation of energy-momentum in …

Einstein derived the "energy-momentum theorem… concerning 'material processes'." In Einstein's 1914 theory the "energy tensor" T is a symmetric tensor of rank two. T is represented by a mixed volume tensor . The generally covariant equations that represent energy-momentum conservation for matter in Einstein's notation are: where,

Einstein׳s physical strategy, energy conservation, …

Given Einstein׳s commitment to a symmetric material stress–energy tensor and employment of a symmetric non-canonical gravitational stress–energy tensor above, it is perhaps lucky that the Entwurf theory׳s canonical stress–energy tensor is (with an index moved with g μ ν) symmetric, in that he could adopt the canonical definition of ...

Defining first ionisation energy. Definition. ... Al: 1s 2 2s 2 2p 6 3s 2 3p x 1: 1st I.E. = 577 kJ mol-1: The 3p electron in aluminium is slightly more distant from the nucleus than the 3s, and partially screened by the 3s 2 electrons as well as the inner electrons. Both of these factors offset the effect of the extra proton.
