Study Notes
States of Matter
- Three states of matter: solid, liquid, and gas, each exhibiting unique particle motion.
- Particle motion is influenced by distance between atoms; increased distance allows more space for greater motion.
Sublimation
- Sublimation refers to the direct transition from solid to vapor without passing through the liquid state.
- Common substances that undergo sublimation include dry ice, naphthalene balls (mothballs), iodine, and ammonium chloride.
- Example process: Heating camphor or ammonium chloride in a covered dish results in vaporization, with vapors condensing back into solid form when they contact cooler surfaces.
- Mnemonic for sublimation: "Subtract Liquid phase" emphasizes that sublimation skips the liquid state completely.
