The heat of vaporization (also known as enthalpy of vaporization) is the amount of energy required to convert a unit mass of a substance from a liquid into a vapor at a constant temperature and pressure. For elements, this value varies significantly and is typically measured in joules per gram (J/g) or kilojoules per mole (kJ/mol).
Morton Gurtin was a prominent American mathematician, primarily known for his work in the fields of applied mathematics and mathematical physics. He made significant contributions to continuum mechanics, particularly in the areas of phase transitions, thermodynamics, and the development of mathematical models for materials. His work often involved the use of variational principles and computational methods to solve complex problems related to the behavior of materials under various conditions.
Otto Redlich was an Austrian physicist known for his work in the field of thermodynamics and the study of heat and temperature. He made significant contributions to the understanding of thermodynamic properties and their applications in various physical processes. His name is sometimes associated with the Redlich-Kwong equation of state, which is a cubic equation used to describe the behavior of gases and liquid mixtures.
Pierre Duhem (1861-1916) was a French physicist, philosopher of science, and historian of science, known for his contributions to the philosophy of science, particularly in the areas of thermodynamics and the philosophy of physics. He is best known for formulating the Duhem-Quine problem, which highlights the complexity of testing scientific theories due to the interconnectedness of hypotheses and auxiliary assumptions.
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.
In the context of thermodynamics, material properties refer to the characteristics of a material that define its behavior in response to changes in temperature, pressure, and other environmental conditions. These properties are critical for understanding how materials will perform in various applications, particularly in areas such as engineering, materials science, and physics.
Wolfgang Pauli (1900-1958) was an influential Austrian theoretical physicist who is best known for his work in quantum mechanics. He is particularly renowned for formulating the Pauli Exclusion Principle, which states that no two identical fermions (such as electrons) can occupy the same quantum state simultaneously. This principle is fundamental to the structure of atoms and explains a wide range of physical and chemical phenomena, including the behavior of electrons in atoms and the stability of matter.
An Experimental Enquiry Concerning the Source of the Heat which is Excited by Friction by
Wikipedia Bot 0 1970-01-01

"An Experimental Enquiry Concerning the Source of the Heat which is Excited by Friction" is a significant work by the English scientist Benjamin Thompson, also known as Count Rumford. Published in 1798, the paper presents experimental investigations into the nature of heat generated by friction and challenges the prevailing caloric theory of heat at that time. In his inquiries, Rumford conducted a series of experiments to demonstrate that heat can be generated mechanically.
In physics, the term "residual property" can refer to various concepts depending on the context, but it is most commonly associated with materials science, thermodynamics, and fluid mechanics. Here are a couple of common interpretations: 1. **Residual Stress**: This refers to internal forces that remain in a material after the original cause of the stresses has been removed. Residual stresses can significantly affect the material's strength, durability, and overall performance.
Specific heat capacity, often simply referred to as specific heat, is a physical property of a substance that measures the amount of heat energy required to raise the temperature of a unit mass of that substance by one degree Celsius (or one Kelvin). The specific heat capacity is typically denoted by the symbol \( c \) and is expressed in units such as joules per kilogram per degree Celsius (J/kg·°C) or joules per kilogram per Kelvin (J/kg·K).
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.
Thermodynamic activity is a measure of the "effective concentration" of a species in a solution, taking into account interactions between particles. It provides a way to understand how the presence of other components in a mixture influences the behavior of a specific component compared to an ideal situation, where components behave independently. In ideal solutions, the activity (\(a\)) of a species is equal to its molar concentration (\(C\)).
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.
Volumetric heat capacity, often denoted as \( C_v \), is a measure of a material's ability to store thermal energy per unit volume for a given temperature change. It quantifies how much heat is required to raise the temperature of a unit volume of a substance by one degree Celsius (or one Kelvin).
Water activity (aw) is a measure of the availability of water in a substance for microbial growth, chemical reactions, and biochemical processes. It is defined as the ratio of the partial vapor pressure of water in a material to the partial vapor pressure of pure water at the same temperature. Water activity values range from 0 to 1, with pure water having an aw of 1.0.
Temperature scales are systems used to measure and express temperature. Several temperature scales have been developed over time, each with its own creators and historical context.
Alfred Ubbelohde (1890-1972) was a prominent German chemist known for his work in the field of physical chemistry, particularly concerning the properties of liquid and solid states of materials. He made significant contributions to the study of solutions, particularly focusing on the behavior of polymers and colloidal systems. His research played a crucial role in advancing the understanding of thermodynamics and kinetics in chemistry.
Bernard H. Lavenda is an American physicist known for his work in theoretical physics, particularly in statistical mechanics and the physics of complex systems. He has contributed to the understanding of various physical phenomena and has authored several papers and books on these topics. Lavenda is also recognized for his efforts in teaching and promoting science, often addressing the philosophical implications of physics.

Constantin Carathéodory (1861–1950) was a Greek mathematician known for his significant contributions to various areas of mathematics, particularly in real analysis, measure theory, and the calculus of variations. He made important advancements in the theory of functions of a real variable, the foundations of measure theory, and the development of the theory of functions of several complex variables.

Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.Figure 1. Screenshot of the "Derivative" topic page.
