Study Notes
Properties of Matter
- A golf ball has more mass than a tennis ball due to containing more matter.
- Water has a melting point of 0°C, highlighting a physical property.
- Substances that form vapors are typically found in liquid or solid states at room temperature.
States of Matter
- Liquids have an indefinite shape but a definite volume.
- Physical changes, such as boiling, alter physical properties.
- Corroding iron results in a change of the substance's identity.
Mixtures and Compounds
- Soil is an example of a heterogeneous mixture.
- Stainless steel represents a homogeneous mixture.
- Filtration separates liquids from solids in heterogeneous mixtures.
- Mixture separation relies on differences in physical properties.
- Pure air can be classified as a mixture; pure water is a compound.
Classification of Materials
- Mayonnaise is classified as a mixture.
- Silver is an example of a substance.
- Water (H₂O) represents a compound.
- Potassium's chemical symbol is derived from its Latin name.
Periodic Table Insights
- Elements in the same vertical column (group) of the periodic table have similar chemical and physical properties.
- Similarities in properties result from elements being in the same group.
Chemical Changes
- The fermenting of cheese illustrates a chemical change.
- To confirm a chemical change has occurred, it is essential to check the composition before and after the change.
- Yellow-brown discoloration of paper exposed to sunlight likely indicates a chemical change.
- Boiling an egg is an example of a chemical change.
Conservation of Mass
- Grinding an iron nail into powder does not alter its mass; it remains the same (176 grams).
