Notes

Nature of Concern:

Physical priorities: These pertain to properties or characteristics that are primarily related to the physical aspects of a substance or system. This could include factors like temperature, pressure, volume, density, and state of matter (solid, liquid, gas).
Chemical priorities: These relate to the chemical composition, reactions, and transformations of substances. Chemical priorities focus on elements, compounds, bonds, and the interactions between different substances at the molecular level.
Dominant Sciences:

Physical priorities: They are often emphasized in fields such as physics, engineering, and material science where understanding and manipulating physical properties are critical.
Chemical priorities: These are central to chemistry and related disciplines where the focus is on the composition, structure, properties, and reactions of substances.
Applications:

Physical priorities: They are frequently applied in designing materials, constructing machinery, analyzing physical systems (like thermodynamics), and solving engineering problems related to mechanics, heat transfer, and fluid dynamics.
Chemical priorities: These are applied in fields such as pharmaceuticals, materials science, environmental science, and chemical engineering to design new molecules, understand reactions, develop new materials, and address issues like pollution and waste management.
Units of Measurement:

Physical priorities: Typically involve units such as meters, kilograms, seconds, joules, pascals, etc., which are commonly associated with physical quantities.
Chemical priorities: Often involve units such as moles, grams, liters, Celsius or Kelvin for temperature, and various energy units like kilojoules per mole, which are commonly associated with chemical quantities and reactions.
Approach to Analysis:

Physical priorities: Analysis often involves principles of classical mechanics, thermodynamics, and other physical laws to describe and predict the behavior of systems based on their physical properties.
Chemical priorities: Analysis frequently involves understanding chemical bonds, reaction mechanisms, and molecular interactions to predict and manipulate chemical reactivity and behavior.
