Answers To CP Questions For Matter - Properties And Change

ChemistryWiki | RecentChanges | Preferences

Here is the answers to CP Questions for Matter - Properties and Change

1) Extensive physical property

2) Do NOT rearrange/reorganize

3) When the particles do not rearrange but it is an observation of how the particle is made or the affect of how it is made up. Example include hardness, density, melting/freezing/boiling point.

4) Law of Conservation of Mass and Law of Conservation of Energy

5) Solid, liquid, gas and plasma

6) No Particles DO NOT rearrange in a phase change since it is a physical change.

7) Temperature is the average kinetic energy of all the particles in a substance.

8) The particles in the solid and liquid phase have not obtained enough energy to overcome their IMF (Intermolecular Forces) so their particles influence each other.
Gas particles have obtained enough energy to overcome their IMF and each particle does not influence another particle. (that is a lie but for now it is OK).

9a) it does not have enough energy to push against the IMF so it does not move significantly in 3-D space but instead vibrates in place.
9b) Gas particles have enough energy to overcome their IMF and are not influenced by other particles so they can move anywhere in 3-D space (actually all particles follow the same rule of movement but gas have not other influences).

10) Permanent color change, Energy change, precipitate formation, and bubble observation (gas formed/odor detected).

10a) A balloon of gas where the "skin" is water molecules.

10b) A solid formed in a solution.
