States of Matter 200
Describe what the particles are doing in a solid and a liquid.

27. States of Matter 200
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.

States of Matter 400
Why a gas is able to change its volume?

31. Why a gas is able to change its volume?
States of Matter 400
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.

49. Why can most chemical changes not be undone?
All 300
Why can most chemical changes not be undone?

50. Why can most chemical changes not be undone?
All 300
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.

55. FINAL JEOPARDY

56. Final Jeopardy
Describe how the motion and arrangement of the particles changes as a substance freezes.

57. Final Jeopardy
Describe how the motion and arrangement of the particles changes as a substance freezes.
As a substance freezes the particles begin to slow down and move closer to each other. As the particles slow down more and more they begin to bond to each other and eventually become tightly packed and only vibrating in place.
