Study Notes
States of Matter
- Solid: particles are closely packed and have a fixed shape and volume
- Liquid: particles are close together but are free to move past each other, takes the shape of its container
- Gas: particles are widely spaced and are free to move in any direction, has neither a fixed shape nor volume
- Plasma: high-energy state of matter where atoms are ionized, often found in stars and lightning
Physical Properties
- Mass: a measure of the amount of matter in an object, remains constant regardless of its state
- Volume: the amount of space occupied by an object or substance, can change depending on its state
- Density: mass per unit volume, can be used to identify substances
- Buoyancy: the ability of an object to float or sink in a fluid, dependent on its density relative to the fluid
Sublimation
- Sublimation: the process by which a substance changes directly from a solid to a gas, without going through the liquid phase
- Examples: dry ice (solid carbon dioxide), iodine crystals, and ammonium chloride
-
Factors affecting sublimation:
- Temperature: increases sublimation rate
- Pressure: decreases sublimation rate
- Surface area: increases sublimation rate
- Concentration: increases sublimation rate

- Buoyancy is the ability of an object to float or sink in a fluid, dependent on its density relative to the fluid.
Sublimation
- Sublimation is the process by which a substance changes directly from a solid to a gas, without going through the liquid phase.
- Examples of sublimation include dry ice (solid carbon dioxide), iodine crystals, and ammonium chloride.
- Factors affecting sublimation rate include:
- Temperature, which increases the sublimation rate
- Pressure, which decreases the sublimation rate
- Surface area, which increases the sublimation rate
- Concentration, which increases the sublimation rate
