Study Notes
Changes in Matter
- Matter changes due to variations in molecular behavior; molecules can be close together or move apart freely.
- Water is a prime example of matter transitioning between different states: solid (ice), liquid (water), and gas (water vapor).
Physical Changes in Matter
- Matter can undergo physical changes affecting its size and shape or altering its form.
- Size or Shape Change: Crumpling a piece of paper results in a new size and shape compared to its original form.
- Form Change: Liquid water can freeze to become ice cubes, showcasing a transformation in physical state.
