- physical properties
- are those properties that can be observed without changing the make-up,or identity, of the matter.
- gas
- The particles of a substance move fastest when the substance is in a gaseous state- so fast that they are able to overcome the attraction between them and separate from each other entirely. Takes on the shape and volume of its container, and can flow (through a room, for example)
- solubility
- ability of one substance to dissolve in another
- vaporization
- changing from liquid state to a gaseous state
- boiling point
- The temperature at which a liquid is converted to a gas at atmospheric pressure
- melting point
- The temperature at which a given substance will change from a solid to a liquid.
- ductility
- the abitilty of a substance to be pulled into thin threads without breaking
- freezing point
- the temperature at which a substance changes from a liquid to a solid state.
- electrical conductivity
- how well a substance allows electricity to flow through it.
- density
- amount of mass in given volume of air
- condensation point
- the temperature at which a gas condenses into a liquid.
- malleability
- ability to be hammered or pounded into thin sheets or a shape (gold)
- liquid
- The particles of a substance move even faster when the substance is in a liquid state. As a result, the particles in a liquid can over come some of the attraction between them, which allows the particles to flow past one another. Holds the shape of the container, keeps the same volume, and can flow.
- solid
- The particles of a substance in its solid state vibration in place, but the vibration isn't great enough to overcome the attraction between the particles and cause them to separation. Keeps its own shape and volume
- chemical properties
- properties that describe matter based on its ability to change into a new kind of matter with different properties.
