Enthalpy:
Enthalpy is a fundamental concept in thermodynamics, especially in chemical reactions and physical processes involving heat exchange. To everyday people, enthalpy might not be a common term. However, it’s closely related to the idea of heat content or energy content. When you think about everyday activities like cooking, for example, enthalpy comes into play. When you cook food, you’re applying heat energy to it, which causes chemical reactions to occur, changing the food’s state and structure. Think about boiling water to cook pasta; the heat added increases the enthalpy of the water, causing it to change from a liquid to a gas phase. In technical language, particularly in chemistry, enthalpy (symbolized as H) represents the total heat content of a system at constant pressure. It includes both the internal energy of the system and the product of pressure and volume.
Barometer:
A barometer is an instrument used to measure atmospheric pressure. This knowledge is based on understanding physics and weather-related concepts. To everyday people, a barometer is often associated with weather forecasting. People might say “The barometer is falling,” meaning that atmospheric pressure is decreasing, which typically indicates an approaching storm. For example, if someone looks at the sky and notices dark clouds and a drop in the barometer reading, they might predict that it’s going to rain soon. In chemistry, a barometer is still an instrument used to measure atmospheric pressure, but it’s also tied to gas laws and the behavior of gases. Chemists use barometers to understand the relationship between pressure and the volume of a gas, which is fundamental to the study of gases. The everyday understanding of a barometer as a weather instrument might initially make it easier for students to grasp its purpose in a chemical context. However, there might be challenges in transitioning from the weather-related concept to the more abstract and mathematical principles of gas behavior in chemistry. Connecting the two contexts and understanding the underlying principles can facilitate learning but might require some adjustment in perspective.

Oxidation:
I have heard this word when people talk about things like rust, as rust is caused by oxidation. When I think about oxidation, I always think about how The Statue of Liberty is green. According to the book, oxidation is a process in which an element’s oxidation number is increased by the loss of electrons. Oxidation is an important chemical process to chemists as oxygen is a main gas in our atmosphere. The everyday and technical meanings of oxidation are very similar as they are the same thing. The difference is that most people may not know that rust or the reason the Statue of Liberty is green is because they are oxidized.
Reduction:
I have seen this word in many classes, like math. In everyday terms, reduction is subtracting or reducing something, such as numbers or people. To chemists, reduction is the process in which an element’s oxidation number is decreased by the gain of electrons. The technical and everyday definitions of reduction are the same; it is just what is being reduced that is different. The everyday term is more broad, while the chemistry definition is specific. As the two definitions are very similar, I feel as though I will be able to remember them easily.

Acid according to Chapter 7, is a substance that will dissolve in water to yield hydronium ions. Acids may be classified as strong (fully react with water) or weak (partially react with water) based on generation of hydronium ions. An everyday example of an acid that comes to mind is that of citric acid from fruits like lemons. This is a weak and organic acid, although I would originally assume it would be a strong acid based on eating lemons (which I love!).
Base according to Chapter 7, is a substance that dissolves in water to yield hydroxide ions. Bases may be classified as strong (completely dissociate in water) or weak (partially dissociate in water). An everyday example of a base is baking soda or sodium bicarbonate. This makes sense to me as I know you can utilize baking soda to subdue acids when cooking.
For both acids and bases, I recall that they are scaled on pH ranging from 1 (Acidic) to 14 (Basic) with 7 being the median (Neutral). For my current work as an RN, I often assess the pH or the CO2/HCO3 level of a patient to figure out if they are respiratory or metabolically acidotic or alkalotic (basic) to guide treatment.
