2. Pressure tank - Wikipedia

   en.wikipedia.org/wiki/Pressure_tank

   The diaphragm or bladder may itself exert a pressure on the water, but it is usually small and will be neglected in the following discussion. Case 1 is an empty tank at the charging pressure P c (gauge). The total volume of the tank is V t. Case 2 is a tank in use, with the air pressure at pressure P (gauge) and a water volume of V. Referring ...

3. Hagedorn temperature - Wikipedia

   en.wikipedia.org/wiki/Hagedorn_temperature

   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 ...

4. Gas thermometer - Wikipedia

   en.wikipedia.org/wiki/Gas_thermometer

   Consider a graph of pressure versus temperature made not far from standard conditions (well above absolute zero) for three different samples of any ideal gas (a, b, c). To the extent that the gas is ideal, the pressure depends linearly on temperature, and the extrapolation to zero pressure occurs at absolute zero. [ 3 ]

5. Temperature - Wikipedia

   en.wikipedia.org/wiki/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 ...

6. Absolute zero - Wikipedia

   en.wikipedia.org/wiki/Absolute_zero

   One model that estimates the properties of an electron gas at absolute zero in metals is the Fermi gas. The electrons, being fermions, must be in different quantum states, which leads the electrons to get very high typical velocities, even at absolute zero. The maximum energy that electrons can have at absolute zero is called the Fermi energy ...

7. Zero-coupon bonds: What they are, pros and cons, tips to invest

   Zero-coupon bonds pay no interest over time but are sold at a discounted face value. Zeros may be a good option for investors looking to meet a financial goal down the road, as they lock in a set ...
