Physical Science

1. the measure of the pull of gravity on an object
4. the process in which a substance changes size, shape, or state of matter but does not create a new kind of matter
7. the ends of a magnet where force is the greatest
8. the process in which matter changes and creates a new kind of matter with different properties
10. the positive and negative particles that carry electricity on an atom
16. a characteristic of matter that can be observed only when matter is changed into a different kind of matter
17. the form of matter in which molecules slide past each other, but remain close together
18. anything that has mass and takes up space
19. a temporary magnet created using electricity

2. materials that do no allow electric current or heat to pass through easily
3. an object that attracts some metals
5. a characteristic of matter that can be measured or observed without changing matter into something new
6. the amount of space that matter takes up
9. the smallest particle of matter
11. opposite magnet poles do this
12. materials that allow electric current to pass through easily
13. a single particle of matter made up of 2 or more atoms joined together
14. the form of matter in which molecules move quickly and have no pattern
15. the form of matter in which the molecules are packed closely together and have a regular pattern
18. the amount of matter in an object
20. the same magnetic poles do this
