   Compared to general-service incandescent lamps giving the same amount of visible light, CFLs use one-fifth to one-third the electric power and may last eight to fifteen times longer. [12] Newer phosphor formulations have improved the perceived color, with "soft white" CFLs judged subjectively similar to standard incandescent lamps. [ 13 ]

   The observation of minutes to hours of X-ray flashes after a short gamma-ray burst is consistent with small particles of a primary object like a neutron star initially swallowed by a black hole in less than two seconds, followed by some hours of lesser energy events, as remaining fragments of tidally disrupted neutron star material (no longer ...

   One: all gas particles behave in a similar way, influenced by gravity and by collisions with one another. Two or three: electrons , ions , protons and neutrons can be distinguished by the sign and value of their charge so that they behave independently in many circumstances, with different bulk velocities and temperatures, allowing phenomena ...

6. Thermal expansion - Wikipedia

   en.wikipedia.org/wiki/Thermal_expansion

   A number of materials contract on heating within certain temperature ranges; this is usually called negative thermal expansion, rather than "thermal contraction".For example, the coefficient of thermal expansion of water drops to zero as it is cooled to 3.983 °C (39.169 °F) and then becomes negative below this temperature; this means that water has a maximum density at this temperature, and ...
