Matter Lesson 1

3. Different phases (forms) in which matter can exist - solid, liquid, gas, plasma
6. (human level) Level of matter large enough to be seen, handled and measured.Example: beaker filled with water
7. The phase of matter in which a substance has a variable shape and a definite volume.
8. The measure of the space occupied by an object. Units of milliliters (mL) and liter (L) for liquids in the laboratory. Units of cubic centimeters (cm3) for solids in the laboratory.
9. (particulate level) Level of individual particles that make up all matter – level of atoms and molecules. Represented by molecular diagrams such as the one shown below for water.
13. A measure of the quantity of matter in an object.
14. The phase of matter in which a substance has a variable shape and a variable volume.
15. Clearly defined or determined.

1. 1. All matter is made of particles that are in constant motion. 2. The faster the particles move, the higher the temperature of the substance. 3. At the same temperature, more massive particles move slower than less massive particles.
2. Capable of change or alteration.
4. A state of matter in which the particles are free to move past one another (flow).
5. The phase of matter in which a substance has both definite shape and a definite volume.
10. Anything that has mass and occupies space (i.e., has a volume).
11. The ability of particles to move closer together as pressure is applied.
12. The phase of matter made of electrically charged particles that is able to conduct electricity. Has a variable shape and a variable volume.
