The Hagedorn temperature was discovered by German physicist Rolf Hagedorn in the 1960s while working at CERN. His work on the statistical bootstrap model of hadron production showed that because increases in energy in a system will cause new particles to be produced, an increase of collision energy will increase the entropy of the system rather than the temperature, and "the temperature ...
Plots of pressure vs temperature for three different gas samples extrapolated to absolute zero. The ideal gas law is based on observed empirical relationships between pressure (p), volume (V), and temperature (T), and was recognized long before the kinetic theory of gases was developed (see Boyle's and Charles's laws). The ideal gas law states ...
Ultra-high-performance lamp. An ultra-high-performance lamp, often known by the Philips trademark UHP, is a high-pressure mercury arc lamp. [1] These were originally known as ultra-high-pressure lamps, [2] [3] because the internal pressure can rise to as much as 200 atmospheres when the lamp reaches its operating temperature.
Absolute zero is the lowest limit of the thermodynamic temperature scale; a state at which the enthalpy and entropy of a cooled ideal gas reach their minimum value. The fundamental particles of nature have minimum vibrational motion, retaining only quantum mechanical, zero-point energy -induced particle motion.
A quantum critical point is a point in the phase diagram of a material where a continuous phase transition takes place at absolute zero.A quantum critical point is typically achieved by a continuous suppression of a nonzero temperature phase transition to zero temperature by the application of a pressure, field, or through doping.
OMG—what a little cutie! Marshmallow is having a ball (pun intended) chasing the Christmas ornaments, and her family gets major brownie points for letting the puppy play.It's a plastic ornament ...
Since the slope shown here reaches the horizontal limit of 0 as T → 0 then the implication is that ΔS → 0, which is the Nernst heat theorem. The significance of the Nernst heat theorem is that it was later used by Max Planck to give the third law of thermodynamics , which is that the entropy of all pure, perfectly crystalline homogeneous ...
The electric vehicle market could get a huge influx of cheaper cars — but not fresh from the factory. In its latest EV intelligence report, consumer research firm J.D. Power projects that a ...
