What is the scientific name for the study of the structure and behavior of matter?

  1. Astronomy

  2. Biology

  3. Chemistry

  4. Geology

The correct answer is: Chemistry

Chemistry is the study of the structure and behavior of matter at the atomic and molecular level. It deals with exploring the composition, properties, and reactions of different substances. Astronomy (option A) is the study of celestial objects and phenomena in space. Biology (option B) focuses on living organisms and their structures, functions, and evolution processes. Geology (option D) is the study of the Earth's physical structure and substance. These options do not involve the study of matter at its molecular level, making them incorrect answers for this question.
