5. Define temperature. ______
6. Define absolute zero ______
7. Complete the chart below. Include the appropriate units for each temperature scale.
Fahrenheit / Celsius / KelvinWater Boils/Condenses
Water Freezes/Melts
Absolute Zero
8. An object is heated up. What happens to its molecules? ______
9. What is “cold”? ______
10. The 4 states of matter are listed below. Under each, draw a picture showing the molecules of that state. Use pluses & minuses instead of dots for the state with ions. Draw arrows to show the energy trend and arrows to show the density trend (increasing or decreasing). Write a note about the shape and volume, and write “fluid” under the fluids.
Solid Liquid Gas Plasma
Fluid? ______
Definite: ______
Increasing Energy
Denser
11. Solid à Gas ______Gas à Solid ______
12. Define diffusion ______
13. What happens to particles in a plasma? ______
14. Kelly is having a hard time opening a jar of spaghetti sauce, so she runs the lid under hot water. Pow! The jar opens. Why did this work and what theory does it relate to? (c.s.) ______
______
15. Absorb heat = endothermic release heat = ______
16. What 3 phase changes are endothermic? ______
17. What 3 phase changes are exothermic? ______
18. Define thermal expansion ______
19. Draw a heating curve below. Identify each segment of the graph & label each axis.
20. Explain why the temperature stops increasing at two points. (c.s.) ______
21. Draw a cooling curve below. Identify each segment of the graph & label each axis.
22. Evaporation is a (warming/cooling) process, so it’s (exothermic/endothermic).
