1. This model best represents which phase of matter? Solid, liquid, gas, plasma

2. gas

3. To change matter from a solid to a liquid, what needs to happen? --liquid needs to be added --heat needs to be removed --heat needs to be added --energy needs to be removed

4. --heat needs to be added

5. In order for conduction of heat to occur, what needs to be present? --ONLY two areas of different temperature --contact between MORE THAN two areas of different temperature --ONLY two areas of different temperature that are touching --AT LEAST two areas of different temperature are touching

7. This model shows which phase of matter? solid, liquid, gas, plasma

8. --liquid

9. When a hot washer is placed in room temperature (RT) water, --hot washer molecules take energy from RT water --hot washer molecules give energy to RT water molecules --the water and washers stay the same temperature --the washer will heat up

10. --hot washer molecules give energy to RT water molecules

11. Thermal energy is --heat in matter --kinetic energy in matter --kinetic energy and energy of attraction in matter --energy of attraction in matter

12. --kinetic energy and energy of attraction in matter

13. Temperature is the --measure of average kinetic energy in molecules in a system --measure of how heat is transferred between systems --conduction of heat between systems --measure of seasons

14. --measure of average kinetic energy in molecules in a system

15. In ice water, energy water gains is transferred to ice & the temperature stays the same. True or False?

16. True

17. As ice water is heated the temp will increase when there are two phases of matter present. True or False?

18. False

19. The image represents which phase of matter? solid, liquid, gas, plasma

20. solid

21. As ice water is heated, the temp will increase when there is one phase of matter present. True or False?

22. true

23. As water is heated, the temp increases because --molecules gain kinetic energy and move faster --the molecules energy of attraction increases --the molecules slow down and get closer to each other --the molecules get bigger and hold more heat

24. --molecules gain kinetic energy and move faster

25. As heat is added to a solid, the molecules gain --energy which allows condensation to occur --attraction for each other and decrease in volume --kinetic energy so that freezing can occur --enough energy to change position & change to liquid

27. As heat is removed from matter, evaporation & melting occur as molecular motion increases. True or False?

28. False

29. Heat energy always wants to move from areas that are colder to areas that are warmer. True or False?

30. False
