BrainPop—Matter Changing States Glue this side down into your notebook using only 4 dots of glue
“4 dots are a lot!!”
1. ____________________is anything that has massor takes up space.
2. The basic states of matter are
______________,_________________,and _____________________. 3.
_______________ is a good example of matter because its three states are all pretty common.
4. Like all matter, water changesstates due to changes in___________________________and ____________________________. 5. But its _________________properties remain the same—amolecule of ice is the same as a molecule of water. 6. State change is purely a _____________________ change. 7. Molecules of ice are bonded tightly to one another, in a structure called a _________________lattice. 8. Thesemolecules all contain _________________,and that energy makes them to vibrate! 9. When you ____________the ice, you give these molecules more energy. 10. They begin ________________faster and faster. 11. Finally they break free of their _________________. 12. When all the bonds have ______________,the water molecules are free to flow past one another. 13. And the ice is now liquid water. That’s called __________________. 14. The temperature at which a solid substance melts into a liquid is called its ____________ ___________.
15. Every element or compound has its own Word Bankmelting _____________ point. Attracted Boiling Bonds Breaking Chemical Climbs Constant Crystal Dry ice Energy Fusion Gas Heat Ice Liquid Matter Melting Melting Point More Physical Pressure Randomly Rising Solid Stays Sublimation Temperature Thermometer Unique Vaporization Vibrating Water 0 212
16. The melting point of water is ________degreesCelsius or 32 degrees Fahrenheit. 17. If you stick a __________________________in the ice as it melts, you’ll notice something interesting. 18. The ice starts out at -10 degrees, and, as it is heated, the temperature ________________to 0 degrees Celsius. 19. But then, it just ___________at 0—even though the flame on the stove is on full-blast! 20. The temperature doesn’t start _______________again until all the ice melts. 21. As long as there is some ice left, all that extra energy goes into ___________________the bonds that hold the crystal lattice together. 22. This extra energy is called the heat of ______________. 23. Gasmolecules have ___________energy than liquid molecules. 24. Liquid molecules are ___________________to one another and tend to clump together. 25. But gas molecules bounce around _________________. 26. To turn a liquid into a gas, you’ve got to add enough energy to _____________________the forces of attraction between those molecules! 27. That energy is called the heat of ___________________________.
28. When we add heat to water, its temperature rises until it hits the________________point—the point where it starts turning into a gas. 29. For water that is 100 degreesCelsius, or ____________degreesFahrenheit. 30. The temperature stays ______________until all of the water turns to vapor. 31. Sometimes substanceschange directly from a solid into a gas. That’s called ______________________. 32. It doesn’t usually happen with water, but you can see it with something called ________ _________.
