For example, in n-doped semiconductor, as the doping concentration is increased, electrons populate states within the conduction band which pushes the Fermi level to higher energy. In the case of degenerate level of doping, the Fermi level lies inside the conduction band. The "apparent" band gap of a semiconductor can ... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Thermal velocity or thermal speed is a typical velocity of the thermal motion of particles that make up a gas, liquid, etc. Thus, indirectly, thermal velocity is a measure of temperature. Technically speaking, it is a measure of the width of the peak in the Maxwell–Boltzmann particle velocity distribution. Note that in... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Gas kinetics is a science in the branch of fluid dynamics, concerned with the study of motion of gases and its effects on physical systems. Based on the principles of fluid mechanics and thermodynamics, gas dynamics arises from the studies of gas flows in transonic and supersonic flights. To distinguish itself from oth... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
It is often modeled as a Poisson process, in which the probability of a collision in a small time interval d t {\displaystyle dt} is d t / τ {\displaystyle dt/\tau } . For a Poisson process like this, the average time since the last collision, the average time until the next collision and the average time between colli... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
An extended periodic table theorises about chemical elements beyond those currently known in the periodic table and proven. The element with the highest atomic number known is oganesson (Z = 118), which completes the seventh period (row) in the periodic table. All elements in the eighth period and beyond thus remain pu... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
However there are numerous exceptions; for example the lightest exception is chromium, which would be predicted to have the configuration 1s2 2s2 2p6 3s2 3p6 3d4 4s2, written as 3d4 4s2, but whose actual configuration given in the table below is 3d5 4s1. Note that these electron configurations are given for neutral a... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Sodium formate, HCOONa, is the sodium salt of formic acid, HCOOH. It usually appears as a white deliquescent powder. | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
They may resemble the elusive metallic hydrogen, but can be made under lower pressures. One possibility is that they could be superconductors. Hydrogen sulfide under high pressures forms SH3 units, and can be a superconductor at 203 K (−70 °C) and a pressure of 1.5 million atmospheres. | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Bismuth (83Bi) has 41 known isotopes, ranging from 184Bi to 224Bi. Bismuth has no stable isotopes, but does have one very long-lived isotope; thus, the standard atomic weight can be given as 208.98040(1). Although bismuth-209 is now known to be radioactive, it has classically been considered to be a stable isotope beca... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Methyl orange is a pH indicator frequently used in titration because of its clear and distinct color variance at different pH values. Methyl orange shows red color in acidic medium and yellow color in basic medium. Because it changes color at the pKa of a mid strength acid, it is usually used in titration of strong aci... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
The metre per second is the unit of both speed (a scalar quantity) and velocity (a vector quantity, which has direction and magnitude) in the International System of Units (SI), equal to the speed of a body covering a distance of one metre in a time of one second. The SI unit symbols are m/s, m·s−1, m s−1, or m/s. | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |

In electrodynamics, circular polarization of an electromagnetic wave is a polarization state in which, at each point, the electromagnetic field of the wave has a constant magnitude and is rotating at a constant rate in a plane perpendicular to the direction of the wave. In electrodynamics, the strength and direction of... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
