Study Notes
Overview of Changes
- Changes can be classified into two main types: chemical changes and physical changes, each with distinct characteristics.
Chemical Changes
-
Burning
- Represents a chemical change due to the transformation of substances into new materials with different properties.
-
Spoiling Milk
- Indicates a chemical change as bacteria alter the composition and qualities of the milk.
-
Boiling
- While often thought of as a physical process, boiling can be considered a chemical change when it involves the alteration of the substance, particularly in some food preparations.
-
Chemicals Changing Colors
- A clear example of a chemical change where the original substances undergo a transformation leading to a different appearance.
Physical Changes
-
Mixing Paint
- A physical change as it combines substances without changing their chemical identities.
-
Freezing
- A physical change whereby a liquid becomes solid without changing its chemical composition.
-
Melting
- Represents a physical change where solids transform into liquids while retaining their original chemical structure.
-
Sublimation
- A physical change that involves a substance transitioning from solid to gas without passing through the liquid phase.
-
Condensation
- A physical change occurring when a gas turns into a liquid, such as water vapor forming droplets.
-
Leaves Changing Color in the Fall
