Hugh Everett III 1970-01-01
Hugh Everett III was an American physicist and mathematician best known for his work in quantum mechanics, particularly for formulating the "many-worlds interpretation" of quantum mechanics in 1957. This interpretation suggests that all possible outcomes of quantum measurements are realized in separate, branching universes, effectively positing the existence of an infinite number of parallel realities.
Ilya Prigogine 1970-01-01
Ilya Prigogine (1917–2003) was a Belgian physical chemist and Nobel laureate best known for his work on Nonequilibrium Thermodynamics and complex systems. He made significant contributions to the understanding of thermodynamic processes far from equilibrium, introducing concepts such as dissipative structures, which are ordered structures that arise in systems that are not in equilibrium. Prigogine's work challenged traditional views of thermodynamics, which were primarily concerned with systems at equilibrium.
Heat capacity ratio 1970-01-01
Schottky anomaly 1970-01-01
The Schottky anomaly refers to a specific behavior observed in the heat capacity of certain materials, particularly in ionic or non-metallic solids, at low temperatures. Named after physicist Walter H. Schottky, the phenomenon arises due to the presence of localized states or defects within the material's crystal structure. In these materials, as the temperature decreases, the heat capacity does not follow the expected behavior for standard Debye or Einstein models, which predict a decrease in heat capacity with decreasing temperature.
Specific energy 1970-01-01
Specific energy is a term used to describe the amount of energy stored or released per unit mass of a substance or system. It is typically expressed in units such as joules per kilogram (J/kg) or calories per gram (cal/g). Specific energy provides a way to compare the energy content of different materials or fuels regardless of their mass, making it a useful metric in fields such as engineering, chemistry, and physics.
Specific volume 1970-01-01
Specific volume is defined as the volume occupied by a unit mass of a substance. It is an important thermodynamic property, particularly in the study of gases, liquids, and solids in various phases and conditions. Mathematically, the specific volume (\( v \)) can be expressed as: \[ v = \frac{V}{m} \] where: - \( V \) is the volume of the substance, - \( m \) is the mass of the substance.
Tammann and Hüttig temperatures 1970-01-01
Tammann and Hüttig temperatures refer to specific thermal properties associated with the behavior of glass-forming liquids, specifically in the study of glass transition and crystallization processes. 1. **Tammann Temperature (T_g)**: This temperature is often associated with the glass transition temperature (T_g) of a material.
Thermal energy 1970-01-01
Thermal energy refers to the internal energy present in a system due to the random motions of its molecules or atoms. It is a form of kinetic energy that arises from the heat and temperature of the matter in question. The more motion the particles have (which generally occurs at higher temperatures), the greater the thermal energy. In practical terms, thermal energy is responsible for the sensations of heat and temperature that we experience in our environment.
Trouton's rule 1970-01-01
Trouton's rule is a principle in physical chemistry that provides an estimate for the entropy of vaporization of a liquid. It states that the entropy of vaporization (\( \Delta S_{vap} \)) of many liquids at their normal boiling points is approximately equal to a constant value, which is about 88 to 100 J/mol·K. This rule holds true for a variety of organic liquids, particularly those that are non-polar or weakly polar.
Vapour pressure of water 1970-01-01
Vapor pressure is the pressure exerted by a vapor in equilibrium with its liquid or solid phase at a given temperature. For water, the vapor pressure increases with temperature. At 20°C (68°F), the vapor pressure of water is approximately 17.3 mmHg (or 2.34 kPa). At 100°C (212°F), the vapor pressure reaches 760 mmHg (or 101.
Volume (thermodynamics) 1970-01-01
In thermodynamics, volume refers to the amount of space that a substance (solid, liquid, or gas) occupies. It is a fundamental property of matter and plays a crucial role in understanding various thermodynamic processes and laws. Volume can be measured in different units, depending on the system of measurement used. Common units include cubic meters (m³) in the SI system, liters (L), and milliliters (mL).
Volume correction factor 1970-01-01
The Volume Correction Factor (VCF) is a coefficient used to adjust the volume of a substance, often liquids, to account for changes in temperature and pressure. The volume of liquids can change significantly with variations in temperature, and since many measurements (like those in the oil and gas industries) require accurate volume readings for billing and inventory purposes, it's essential to correct for these variations.
Latent internal energy 1970-01-01
Latent internal energy refers to the energy stored within a substance that is associated with changes in its phase or state, such as during melting, freezing, vaporization, or condensation. This type of energy is not immediately observable as a change in temperature since it is involved in breaking or forming intermolecular bonds rather than increasing the kinetic energy of the particles.
