Physical Properties:
* Mass: Measured using a balance or scale.
* Volume: Measured using graduated cylinders, beakers, or displacement methods.
* Density: Calculated by dividing mass by volume.
* Temperature: Measured using thermometers.
* Boiling point: Measured using a thermometer and a heating source.
* Melting point: Measured using a thermometer and a heating source.
* Solubility: Measured by dissolving a known amount of substance in a known amount of solvent and observing the amount that dissolves.
* Conductivity: Measured using a conductivity meter.
* Viscosity: Measured using a viscometer.
* Hardness: Measured using a scratch test or a Mohs hardness scale.
Chemical Properties:
* Flammability: Observed by exposing a substance to a flame and observing its reaction.
* Reactivity: Measured by observing the substance's reaction with other substances.
* Combustibility: Measured by observing the substance's ability to burn in the presence of oxygen.
* Corrosion: Measured by observing the substance's reaction to a corrosive agent.
* pH: Measured using a pH meter or pH paper.
Other Methods:
* Spectroscopy: Uses electromagnetic radiation to analyze the composition and structure of matter.
* Chromatography: Separates components of a mixture based on their different affinities for a stationary phase.
* Microscopy: Uses microscopes to view and analyze the structure of matter at a microscopic level.
* X-ray diffraction: Used to determine the arrangement of atoms and molecules in crystals.
Specific Instruments:
* Balances: For measuring mass.
* Thermometers: For measuring temperature.
* Graduated cylinders and beakers: For measuring volume.
