1. Introduction to Matter

2. Sciences Used to be divided into strict categories: Used to be divided into strict categories: physical (nonliving) physical (nonliving) biological (living) biological (living) Chemistry has parts that fall under both categories. Chemistry has parts that fall under both categories. Many sciences are so interrelated that you can’t categorize them in those ways anymore. Many sciences are so interrelated that you can’t categorize them in those ways anymore.

3. Chemistry The study of matter and the changes it undergoes. The study of matter and the changes it undergoes. Chemists use instruments to improve their ability to observe and make measurements. Chemists use instruments to improve their ability to observe and make measurements.

4. Chemistry Chemists work with chemicals (any substance with definite composition). Chemists work with chemicals (any substance with definite composition). All matter has chemical basis whether it is living or nonliving. All matter has chemical basis whether it is living or nonliving.

5. What is Matter? Matter is anything that has mass and takes up space. Matter is anything that has mass and takes up space. “ Everything is made of matter.” “ Everything is made of matter.”

6. Physical Properties of Matter Physical properties can be observed or measured WITHOUT changing the matter. Physical properties can be observed or measured WITHOUT changing the matter. Volume Volume Mass Mass Weight Weight Inertia Inertia Density Density

7. Matter and Volume Volume is the amount of space that is taken up by a form of matter. Volume is the amount of space that is taken up by a form of matter. Liquid is measured using a graduated cylinder- Units are in milliliters. Liquid is measured using a graduated cylinder- Units are in milliliters. Regular Solids are measured by using the formula: length x width x height Regular Solids are measured by using the formula: length x width x height Irregular Solids are measured by using the Water Displacement method. Irregular Solids are measured by using the Water Displacement method.

8. Matter and Mass Mass is the amount of matter in an object. Mass is the amount of matter in an object. The mass of an object WILL NOT change throughout the universe. The mass of an object WILL NOT change throughout the universe. Usually measured in grams (g), kilograms (kg), or milligrams (mg) with a Balance Scale. Usually measured in grams (g), kilograms (kg), or milligrams (mg) with a Balance Scale.

9. Difference Between Weight and Mass Weight is the amount of gravitational force exerted on an object. Weight is the amount of gravitational force exerted on an object. Usually measured in Newtons (N) using a spring scale. 1 N= 100g Usually measured in Newtons (N) using a spring scale. 1 N= 100g

10. Matter and Inertia Inertia is the tendency of an object to resist change in motion. Inertia is the tendency of an object to resist change in motion. Mass is a measure of inertia. Mass is a measure of inertia. The larger the mass, the harder it is to move. The larger the mass, the harder it is to move.

11. Matter and Density Density is the amount of matter in a given space in a certain volume of liquid. Density is the amount of matter in a given space in a certain volume of liquid. A physical property A physical property Density = Mass / Volume Density = Mass / Volume

12. What does density mean? How tightly packed the particles are. How tightly packed the particles are. How much matter (that’s the mass) divided by how much space the matter takes up (that’s the volume) How much matter (that’s the mass) divided by how much space the matter takes up (that’s the volume) Density = __How much matter_(mass)_ How much space taken up (volume) How much space taken up (volume)
