States of Matter Flashcards
1
Q
solid
A
fixed shape and volume, cannot compress, particles vibrate in fixed arrangements
2
Q
liquid
A
fixed volume, constantly changing arrangement, particles slide over each other
3
Q
gas
A
no fixed shape or volume, easily compressed, random arrangement, particles travel in all directions at high speeds, collisions with container = pressure
4
Q
solid to liquid
A
melting, vibrations lead to particles breaking free from neighbours
5
Q
liquid to solid
A
solidifies/ freezes
6
Q
liquid to gas
A
condensing/ evaporation, energy/ particles transferred to surroundings, escaping liquid surface
7
Q
gas to liquid
A
condensing
8
Q
substances with high intermolecular forces have . . .
A
higher melting/ boiling points
