20. Elements, Compounds and Mixtures 400 A solution is also know as this type of mixture.

21. Elements, Compounds and Mixtures 400 A solution is also know as this type of mixture. Homogeneous mixture

22. Elements, Compounds and Mixtures500 Oxygen gas, O2 is an example of a ______________.

23. Elements, Compounds and Mixtures500 Oxygen gas, O2 is an example of a Molecule.

24. States of Matter100 What are the three states of matter?

25. States of Matter100 What are the three states of matter? Solid, liquid, gas

26. States of Matter200 Describe what the particles are doing in a solid and a liquid.

27. States of Matter200 Describe what the particles are doing in a solid and a liquid. Particles in a solid are tightly packed and vibrating in place. Particles in a liquid are tightly packed, but able to slide past each other.

28. States of Matter300 What are three things that are true about the atoms and molecules in all matter?

29. States of Matter300 What are three things that are true about the atoms and molecules in all matter? They are constantly moving. They are all attracted to each other. Move faster at higher temperatures.

30. States of Matter400 Why a gas is able to change its volume?

31. States of Matter400 Why a gas is able to change its volume? The particles of a gas can be forced closer together, or they can spread apart from each other because they are not touching.

32. States of Matter500 Which state of matter has a definite volume, but an indefinite shape?

33. States of Matter500 Which state of matter has a definite volume, but an indefinite shape? Liquid – they can change shape but not volume.

34. Changes of State100 What has to change (either be added or taken away) in order for a change of state to happen?

35. Changes of State100 What has to change (either be added or taken away) in order for a change of state to happen? Heat/energy

36. Changes of State200 When an object changes from a liquid into a solid.

37. Changes of State200 When an object changes from a liquid into a solid. Freezing

38. Changes of State300 Name one change of state that is endothermic.

39. Changes of State300 Name one change of state that is endothermic. Melting, vaporization, sublimation

40. DAILY DOUBLE!

41. Changes of State400 When a person wearing glasses enters a warm house after being outside on a cold day, their glasses fog up because of which change of state?

42. Changes of State400 When a person wearing glasses enters a warm house after being outside on a cold day, their glasses fog up because of which change of state? condensation

43. Changes of State500 What example of vaporization occurs throughout a liquid, not just at its surface?

44. Changes of State500 What example of vaporization occurs throughout a liquid, not just at its surface? boiling

45. All100 Define Endothermic

46. All100 Define Endothermic Heat/energy going in

47. All200 Give an example of a homogeneous mixture.

48. All200 Give an example of a homogeneous mixture. Salt water

49. All300 Why can most chemical changes not be undone?

50. All300 Why can most chemical changes not be undone? Because the substances have been combined chemically, which means they are totally different from how they were when they started. They have turned into something completely new.
