Down
- 1. a fraction created from two measurements that are equal to each other which is used to convert from one unit to another
- 2. state of matter where particles have so much energy they spread apart and fill the container
- 4. anything that has mass and takes up space
- 6. a substance containing only one type of atom
- 8. How closely a set of repeated measurements are to each other
- 9. A value calculated by subtracting the experimental value from the accepted value, dividing the difference by the accepted value, and then multiplying by 100
- 12. How close a measurement is to the true/accepted value
- 16. state of matter where the particles have enough energy to slide past each other
