Study Notes
Forms of Matter
- Energy is NOT a form of matter
Chemical Change
- An example of a chemical change is burning wood, as it involves the transformation of one substance into another
Physical Properties of Matter
- Color, texture, and odor are physical properties of matter
Characteristics of Living Organisms
- Inability to respond to stimuli is NOT a characteristic of living organisms
Physical Change
- Melting of ice is an example of a physical change, as it involves a change of state from solid to liquid without a change in composition
Chemical Properties of Matter
- Flammability is a chemical property of matter, as it determines the ability of a substance to undergo combustion
Scope of Chemistry
- Chemistry deals with the composition, properties, and reactions of matter, making it a central science that intersects with physics, biology, and geology
Chemical Bonds
- Chemical bonds in chemical compounds involve the sharing or transfer of electrons between atoms to form molecules
Chemistry as the Central Science
- Chemistry is called the central science because it provides a foundation for understanding many disciplines, including biology, physics, geology, and medicine
