chemistry
Across
- 4. A derived value that describes an object's mass divided by its volume
- 6. A measure of the average kinetic energy of a substance. A measure of how fast a sample's molecules are moving
- 7. 0.001 L
- 11. variable: The variable that is measured by the scientist. What the independent variable does.
- 13. data: Data that can be measured or counted. Data that describes the quality of something. Cannot be counted.
- 14. A test a scientist does to collect data to support or refute a scientific question or claim.
- 15. The SI unit for measuring mass
- 17. figures: A way of determining the precision of a measurement. A way to know how to round a number without asking the teacher.
- 18. The amount of space a sample of matter takes up.
- 20. data: Data that can be measured or counted
- 22. The measure of the force of gravity acting on an object
- 23. The SI unit for length
- 26. relationship: The relationship between two variables is an direct relationship if when one increases the other increases.
- 27. A unit that can be used to measure any form of energy
- 29. relationships: The relationship between two variables is an inverse relationship if when one increases the other decreases or as one decreases the other increases.
- 30. A visual representation of data that makes trends in the data more evident.
Down
- 1. A scientific prediction based on research, evidence, and/or observation
- 2. analysis (factor labeling): The process of converting from one unit or metric prefix to another unit or metric prefix using conversion factors.
- 3. factor: A fraction used to convert from one unit or metric prefix to another unit or metric prefix.
- 5. centimeter: A derived unit used to measure volume. 1.0 cm2 = 1.0 mL
- 8. variable: The variable of an experiment that the scientist controls. What is being tested.
- 9. A unit that measure of thermal energy
- 10. How close a group of measurements are to each other
- 12. A temperature scale used by chemists and physicists which has no negative numbers.
- 13. the amount or number of something.
- 16. method: The easiest way to describe what a scientists does. A simplified set of steps that can guide an experiment.
- 19. The SI unit for volume.
- 21. unit: A unit that is made from other SI units. EX: Area has a unit of m2 (length x width)
- 24. How close a measurement is to the true value.
- 25. A temperature scales based on the freezing point and boiling point of water.
- 28. 1,000 grams
