Across
- 3. The three ___ of matter, are solid-liquid-and gas
- 4. a measurement of mass AND gravity. It is NOT the same thing as mass even though people get it confused sometimes
- 7. anything that has mass and takes up space. It makes up EVERYTHING around you
- 9. how much MATTER is in an object. The more matter, the more of this there is
- 11. a group of two or more ATOMS that are chemically joined together (matter->atoms->___)
- 13. a hazard in the laboratory, this is one of the reasons we tie hair back and roll up sleeves, the safety symbol for this has flame on it
- 15. to change a gas to a liquid, the particles must be forces to have ____ energy
- 16. a type of mixture in which the proportions are so Unevenly mixed it is VERY EASY to separate the pieces from each other. Think mixing grapes & cherries in a bowl, mixing marshmallows & mentos in a bowl
- 20. a phase change in which the particles slow down and the gas particles in the air slow down and transition into liquid and fall onto your car or on the ground as dew (gas to liquid)
- 22. the curve of that happens in a laboratory equipment when doing measurements with liquid. You should always measure from the BOTTOM of this curve
- 24. a basic substance that can't be simplified any further (think hydrogen, oxygen, neon...periodic table of ____)
- 25. a piece of laboratory safety equipment that should be used anytime there is glass, heat or chemicals
- 28. laboratory equipment used to measure temperature
- 29. What do you have to apply to a state of matter to get the particles to move faster?
- 33. a type of mixture in which the proportions are so evenly mixed it would be VERY hard to separate it. Think sweet tea, coffee with creamer, kool-aid with sugar
- 36. two or more substances that have been physically combined/mixed
Down
- 1. on a phase change diagram, this is on the x-axis and increases as we read the graph from left to right
- 2. if the temperature rises, the particles in a solid start to move how?
- 5. a phase change where the particles are sped up by apply heat (like on a stove), and the particles speed up and a liquid turns into a gas
- 6. means movement
- 8. on a phase change diagram, this is on the y-axis and increases as we read the graph from top to bottom
- 10. if the temperature gets colder, the particles in a gas start to move how?
- 12. This is what should be read carefully before the chemistry lab starts and should be listened to carefully as the teacher gives them
- 14. a phase change where the particles slow down and a liquid changes into a solid
- 17. laboratory equipment that can come as an electronic version or as a triple beam balance
- 18. the state of matter with more energy than a solid, but less energy than a gas
- 19. this type of change is when a state of matter gains or loses enough energy to change to a COMPLETELY different state of matter
- 21. a measurement of how close, after many attempts, the trys were to the TARGET
- 23. a piece of lab equipment that is normally made of class, that has a large opening and holds large amounts of liquids
- 26. a phase change where energy is gained and a solid transforms into a liquid
- 27. to go from a liquid to a solid, to slow the particles down enough, the temperature needs to be ___.
- 30. the state of matter with the most energy
- 31. kinetic _____ is the idea that all the particles inside each of the 3 states of matter are constantly in motion
- 32. the state of matter of the least amount of energy
- 34. To change a solid to a liquid, the particles need ____ energy
- 35. a measurement of how close, after many attempts, the trys were to each other (how close to the center of the target DOESN'T MATTER)
