Each measurement has an amount, a unit for comparison, and an uncertainty. Measurements can be represented in either decimal or scientific notation. Scientists primarily use the SI (International System) or metric systems. We use base SI units such as meters, seconds, and kilograms, as well as derived units, such as liters (for volume) and g/cm3 (for density).

Figure \PageIndex1: (Left) A typical water bottle is 1 liter in volume. (Middle) This Rubik's cube is 5.7cm on each side and has a volume of 185.2cm3 or 185.2mL. (Right) A graduated cylinder is often used to measure volume in the laboratory, and comes in a variety of sizes.

Various types of systems are identified, such as open, closed, and isolated systems, based on how they allow matter and energy transfer. The distinctions between homogeneous and heterogeneous systems are also outlined, along with the significance of intensive and extensive variables.

Boyle's Law explains the inverse relationship between pressure and volume at constant temperature. Charles' Law states that volume is proportional to temperature at constant pressure. Gay-Lussac's Law relates pressure to temperature. These laws combine into the Combined Gas Law.
