Key Concepts

Units of Measurement

Units of measurement are standardized quantities used to express physical properties. They provide a way to quantify and compare different attributes, such as length, mass, volume, and pressure. Understanding the context of these units is essential for interpreting scientific data accurately.

Pressure

Pressure is defined as the force exerted per unit area. It is commonly measured in pascals (Pa), where 1 Pa equals 1 newton per square meter. Pressure is a crucial concept in various fields, including chemistry, as it influences gas behavior and reactions.

Mass

Mass is a measure of the amount of matter in an object, typically expressed in grams (g) or kilograms (kg). It is a fundamental property that affects an object's weight and its behavior in chemical reactions. Understanding mass is vital for stoichiometry and calculating reactants and products in chemical equations.
