Study Notes
Physical Properties
- Blue color is a characteristic identified as a physical property.
- Density measures how much mass is contained in a given volume, confirming its classification as a physical property.
- Solubility indicates whether a substance dissolves in a solvent, which is a physical characteristic.
- Sour taste is a sensory trait and falls under physical properties.
- Hardness determines how resistant a material is to deformation, categorizing it as physical.
- Boiling point signifies the temperature at which a liquid turns to vapor, making it a physical property.
- Luster refers to the way light interacts with the surface of a mineral, a physical property.
- Odor describes the smell of a substance, recognized as a physical property.
- Melting point is the temperature at which a solid becomes a liquid; it's a crucial physical property.
- Physical changes include actions like cutting an apple, heating water to steam, and the melting of ice.
- Evaporation, such as from an ice cube in the sun, is a physical change where liquid turns to gas.
- Mixing salt and pepper results in a physical combination, not a chemical reaction.
- Dissolving sugar or chocolate syrup in water is a physical change as no new substances are formed.
- Inflating a tire represents a physical change related to shape and volume adjustments.
Chemical Properties
- Flammability indicates how readily a substance will burn, classifying it as a chemical property.
- Reactivity with acid, water, and air signifies chemical changes, revealing how substances interact under certain conditions.
- Combustion support implies a substance's ability to sustain a fire, reflecting its chemical properties.
- Changes such as milk souring and baking soda reacting with vinegar showcase chemical reactions and transformations.
- Chemical processes involve rusting of metal (iron) and tarnishing of silver, indicating transformations at a molecular level.
- Growth of grass and digestion of food are examples of chemical changes occurring in nature and organisms.
Scenarios Describing Changes
- Scenario 1 illustrates both physical (size change) and chemical aspects (heat) with bread while baking.
- Scenario 2 depicts a chemical change where bread turns black.
- Scenario 3 involves color changes, which signify chemical reactions.
- Scenarios illustrating physical traits include dry hair and simple shape or color changes without altering the substance chemically.
- Chemical reactions often produce gas or heat, as seen in scenarios with bubbles or color shifts.
True/False Statements
- Evaporation, such as water transforming into gas, is recognized as a physical change.
- Burning wood is classified incorrectly as a physical change; it is chemical.
- Breaking concrete is a confirmed physical change since it doesn't alter its chemical structure.
- Mixing substances can lead to physical changes if no new products are created, while acid rain impacting marble represents a harmful chemical alteration.
