K.
- kelvin; K (after Lord Kelvin, 1824-1907)
-
- The fundamental
SI unit of
thermodynamic temperature defined as 1/273.16 of the thermodynamic
temperature of the triple point of water.
-
- Kepler's 1-2-3 law
-
- Another formulation of
Kepler's third law, which relates the mass m of the primary to a
secondary's angular velocity omega and semimajor axis a:
m o= omega2 a3.
- Kepler's laws (J. Kepler)
-
-
- Kepler's first law
-
- A planet orbits the Sun in an ellipse with the Sun at one focus.
-
- Kepler's second law
-
- A ray directed from the Sun to a planet sweeps out equal areas in
equal times.
-
- Kepler's third law
-
- The square of the period of a planet's orbit is proportional to the
cube of that planet's semimajor axis; the constant of proportionality is
the same for all planets.
-
- Kerr effect (J. Kerr; 1875)
-
- The ability of certain substances to differently
refract light waves whose vibrations are in different directions when the
substance is placed in an electric field.
-
- kilogram; kg
-
- The fundamental
SI unit of
mass, which is the only
SI unit
still maintained by a physical artifact: a platinum-iridium bar kept in the
International Bureau of Weights and Measures at Sevres, France.
-
- Kirchhoff's law of
radiation (G.R. Kirchhoff)
-
- The emissivity of a body is equal
to its absorptance at the same temperature.
-
- Kirchhoff's laws (G.R. Kirchhoff)
-
-
- Kirchhoff's first
law
-
- An incandescent solid or gas under high pressure will produce a
continuous spectrum.
-
- Kirchhoff's second law
-
- A low-density gas will radiate an emission-line spectrum with an
underlying emission continuum.
-
- Kirchhoff's third law
-
- Continuous radiation viewed through a low-density gas will produce
an absorption-line spectrum.
-
- Kirchhoff's rules (G.R. Kirchhoff)
-
-
- loop rule
-
- The sum of the potential differences encountered in a round trip
around any closed loop in a circuit is zero.
-
- point rule
-
- The sum of the currents toward a branch point is equal to the sum of
the currents away from the same branch point.
-
- Kirkwood gaps (Kirkwood)
-
- Gaps in the asteroid belt, caused by resonance
effects from Jupiter. Similar gaps exist in Saturn's rings, due to the
resonance effects of shepherd moons.
-
- Kohlrausch's law (F. Kohlrausch)
-
- If a salt is dissolved in water, the
conductivity of the solution is the sum of two values -- one depending on
the positive ions and the other on the negative ions.
