Matter
Across
- 1. change a change in which one or more substances combine or break apart to form new substances
- 8. involves separating liquids by boiling them. The liquid with the lower boiling point vaporizing first, leaving the other liquid behind
- 9. the measurement of how much mass of a substance is contained in a given volume
- 10. has definite shape and volume
- 16. system of units used by scientist to measure mass
- 18. variable changes or manipulations by scientist (does not depend on other variable - the "cause" of the hypothesis)
- 20. a measure of the force of gravity acting on an object
- 21. anything that has mass
- 23. a neutral group of two or more atoms held together by covalent bonds
- 24. can be measured numerically (height, length, or weight)
- 25. a factor in an experiment or investigation that changes
- 28. variable changes as a result of other variables (depends on other variable - the "effect"
- 29. a measure of how much matter is in an object
Down
- 1. variable a factor or condition in scientific experiments that intentionally kept constant and unchanged to ensure it does not influence the outcome of the experiment
- 2. a substance made of two or more elements chemically combined in a specific ratio or proportion
- 3. change a change that alters the form or appearance of a material but does not make the material into another substance
- 4. a single kind of matter that is pure and has a specific set of properties
- 5. solids quartz with repeating patterns
- 6. observed and generally cannot be measured with a numerical result
- 7. fluid without a definite shape or volume
- 11. property a change that alters the form or appearance of a material but does not make the material into another substance
- 12. to change (something) into a different form or property
- 13. two or more substances that are together in the same place - but their atoms are not chemically bonded
- 14. property a characteristic of a substance that describes its ability to change into different substances
- 15. a pure substance that cannot be broken down into other substances by chemical or physical means
- 17. the basic particle from which all elements are made - the smallest particle of an element that has the properties of that element
- 19. solid not arranged in a regular pattern
- 22. the explanation of scientists based on their current understanding and research
- 26. the amount of space that matter occupies
- 27. mass divided by volume
