Study Notes
Understanding Matter and Its Behavior
- Scientists observe various behaviors of matter and seek to explain why they occur.
- Common observations include the ability to smell food cooking from another room and the expansion of substances when heated.
- Liquids like water transition to gas when heated and can change to solid when cooled, illustrating the effects of temperature on matter.
Hypothesis and Theory Development
- A hypothesis is a preliminary explanation formulated by scientists to address observed phenomena.
- Hypotheses can be tested through experimental investigations to determine their validity.
- When a hypothesis is extensively tested and accepted by the scientific community, it evolves into a theory.
Particle Theory of Matter
- The dominant theory explaining matter's behavior is based on the concept of particles.
- Particles are minute units of matter that make up all substances.
- This theory posits that the arrangement and interactions of these particles account for the various physical properties and behaviors of matter.
