(2) Introduction - States of Matter Flashcards
Differences among the three states of matter (3)
- Arrangement of Particles
- Relative Spacing between Particles
- Relative Motion of Particles
1st variable: S, L, G
S: ordered arrangement
L: disordered arrangement
G: totally disordered arrangement
What can the first variable affect? S, L, G
Shape
S: definite shape
L: indefinite shape
G: indefinite shape
2nd variable: S, L, G. Discuss IMF each
S: tightly packed - stong IMF
L: closer to one another - separated due to weaker IMF
G: far apart - very weak IMF
Three Variables that can be Affected by the Relative Spacing between Particles
- Compressibility
- Volume
- Density
1st variable in RSP: S, L, G. Discuss space
S: incompressible - no spaces
L: slightly compressible - have spaces in between
G: highly compressible - greater distance
2nd variable in RSP: S, L, G
S: definite
L: definite
G: indefinite
Definition of Volume
amount of space occupied by a certain object
has 3D aspects: L, W H
The general rule of volume
The more that the particles are very closer to one another, the more the definite volume.
3rd variable in RSP: S, L, G. Discuss volume
S: very high density - occupies small space
L: high density - occupies smaller space
G: low density - occupies large space
Definition of Density
ratio between mass and volume
direct relationship: d and m
inverse relationship: d and v
3rd variable: S, L, G
S: fixed position, vibration
L: free to move
G: complete freedom for motion
What can the 3rd variable affect? S, L, G
Diffusion
S: extremely slow
L: slow - strong IMF
H: high - random movement
Definition of Diffusion
movement of a substance from HC-LC
passive transport
doesn’t require energy
Transformation of matter from one state to another with the involvement of energy
Phase Change
