The term "bonus stage" can refer to different concepts depending on the context in which it is used: 1. **Video Games**: In many video games, especially platformers or arcade games, a "bonus stage" is a special level or segment where players can earn extra points, lives, or rewards. These stages often provide different gameplay mechanics or objectives compared to the main game, allowing players to enhance their score or gather items.

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).

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).

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" 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.

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.

This work laid the groundwork for later developments in thermodynamics. Black also studied the properties of gases and is credited with the identification of carbon dioxide, which he referred to as "fixed air.

Walther Nernst (1864–1941) was a prominent German physical chemist known for his significant contributions to various areas of chemistry, including thermodynamics, electrochemistry, and chemical kinetics. He is best known for the formulation of the Nernst Equation, which describes the relationship between the concentration of ions in solution and the electrical potential of an electrochemical cell. This equation is crucial for understanding how batteries and galvanic cells operate.

Cryogenic engineering is a specialized field of engineering that deals with the production and application of very low temperatures, typically below -150 degrees Celsius (approximately -238 degrees Fahrenheit or 123 Kelvin). At these temperatures, the properties of materials can change significantly, and many gases become liquids, which can be exploited for various industrial and technological processes. Key aspects of cryogenic engineering include: 1. **Cryogenic Liquefaction**: Processes to convert gases like nitrogen, helium, and hydrogen into liquids.

A cryometer is an instrument used to measure very low temperatures, typically in the cryogenic range, which is generally considered to be below -150 degrees Celsius (-238 degrees Fahrenheit). Cryometers can be used in various scientific and industrial applications, including material testing, fundamental physics research, or in the cooling processes of technologies such as superconductors. Different types of cryometers operate on various principles.

Thermal science is the study of heat, energy transfer, and thermodynamic processes.

Von Babo's law is a principle in biomechanics that relates to the deformation of biological tissues under mechanical stress. It states that the stress (force per unit area) applied to a material is proportional to the resulting strain (deformation) within the elastic limit of that material. In simpler terms, it describes how tissues, such as cartilage or bone, respond to the forces applied to them.

Thin-film optics is the study of light behavior as it interacts with thin layers of materials, typically ranging from a few nanometers to several micrometers in thickness.
