Study Notes
States of Matter
- Gaseous: Lacks definite shape and volume.
- Liquid: Has a definite volume but no definite shape.
- Solid: Possesses both definite volume and definite shape.
- Matter: Defined as anything that has mass and volume.
Changes in Matter
-
Physical Changes: Do not alter the chemical composition of the substance.
- Boiling water
- Ironing a shirt
- Evaporating alcohol
- Sanding a tabletop
- Grinding grain
- Dissolving sugar in water
-
Chemical Changes: Alter the chemical structure of the substance.
- Cooking an egg
- Burning gasoline
- Decomposing water
- Fermentation of fruit juice
Identifying Changes
- Chemical change example: Cooking an egg, evidenced when proteins denature and form a new structure.
- Physical change example: Evaporating water, where the state changes from liquid to gas but the chemical structure remains H2O.
Non-Chemical Change Identifications
- Boiling water is a physical process as it only changes the state from liquid to gas, maintaining the water's composition.
- Dissolving sugar in coffee is purely physical as the sugar can be separated back out.
Key Examples
- Chemical changes include processes like burning, cooking, or rusting, where new substances are created.
- Only boiling water represents a process without chemical change among the listed options.
