J.
joule; J (after J.P. Joule, 1818-1889)
The derived SI unit of energy defined as the amount of work done by moving an object through a distance of 1 m by applying a force of 1 N; it thus has units of N m.
Joule-Thomson effect; Joule-Kelvin effect (J.P. Joule, W. Thomson [later Lord Kelvin])
The change in temperature that occurs when a gas expands into a region of lower pressure.
Joule's laws (J.P. Joule)
Joule's first law
The heat Q produced when a current I flows through a resistance R for a specified time t is given by
Q = I2 R t
Joule's second law
The internal energy of an ideal gas is independent of its volume and pressure, depending only on its temperature.
Josephson effects (B.D. Josephson; 1962)
Electrical effects observed when two superconducting materials are separated by a thin layer of insulating material.
