1. Pure Substances - these are substances that have fixed compositions such as water, air and nitrogen.
2. The properties of Pure Substances are:
- mass
- volume
- temperature
- shape
- boiling point
- density
- melting point
- solubility
- appearance
- texture
- color
- polarity
- these substances have a homogeneous chemical composition
- saturation temperature
3. Tabulate the answers:
Pure Substances
- Appearance - a pure substance is usually one color, the only exception is that if the matter has unusual optical properties
- Melting point - is the temperature at which the pure substance changes from solid to liquid, it is usually in a single temperature or fixed temp.
- Boiling point - is the temperature at the pure substance changes from liquid to gas.
