Study Notes
Chemical Properties
- Define chemical property as the ability or inability of a substance to combine with or change into one or more new substances.
- Silver tarnishing and hydrogen flammability are examples of chemical properties.
- Carbon dioxide's nonflammability and aluminum's reaction with acid are additional chemical properties.
Chemical Changes
- Chemical change refers to the transformation of one or more substances into different substances.
- Apples turning brown in air, rusting of abandoned cars, and burning of paper illustrate chemical changes.
- Sugar dissolving in water and formation of liquid from vapor cooling represent chemical changes as well.
Physical Properties
- Physical properties are characteristics of a material observable without altering its identity.
- Water's boiling point at 100 degrees Celsius and silver's conductivity are examples of physical properties.
- Other physical properties include table salt's melting point at 801 degrees Celsius, diamonds' hardness, and mercury's liquid state at room temperature.
Physical Changes
- A physical change is a reversible change that does not alter the substance's chemical structure.
- Ice melting into water and dissolving sugar in water are classic examples of physical changes.
- Such changes, like becoming easily reversible, are common in physical transformations.
