17
Q

What are the features of ice ?

A
  • low melting point due to weak intermolecular forces
  • very strong. Will not break easily due to regular arrangement of molecules and each molecule makes 4 intermolecular forces
18
Q

What are the special features of water, as a liquid vs solids

A

liquid is more dense than solid, for no specific known reason

19
Q

What are the 2 main ideas in the kinetic theory of matter ?

A
  1. All matter consists of very small particles which are constantly moving, or in a continued state of motion
  2. The degree to which the particles move is determined by the amount of energy they have and their attraction to other particles
20
Q

What are all the state changes involving solids, liquids and gases?

A

see card

  • solid to gas - sublimation
  • solid to liquid - melting
  • liquid to gas - boiling/evaporation
  • liquid to solid - solidifying/freezing
  • gas to liquid - condensation
  • gas to solid - deposition
