Question

1.3a models of the atom
select the best answer for each of the following questions in box 5.
5 - 1 which of the following is not a property of solids?
a. contains separated particles
b. particles vibrate and rotate
c. strong forces hold the particles in position
d. exist as a lattice
5 - 2 which of the following is a property of both solids and liquids?
a. compressible
b. can be disrupted
c. may exist as a lattice
d. particles can flow past one another
5 - 3 which of the following processes requires heat energy to be added?
a. condensation
b. deposition
c. vaporization
d. recombination
5 - 4 which of the following phase changes requires heat energy to be removed?
a. solid to liquid
b. solid to gas
c. gas to plasma
d. gas to liquid

Explanation:

5 - 1: Solids have closely - packed particles, not separated. So a is incorrect.
5 - 2: Both solids and liquids can be disrupted.
5 - 3: Vaporization requires heat addition.
5 - 4: Gas to liquid (condensation) needs heat removal.

Answer:

5 - 1: a. Contains separated particles
5 - 2: b. Can be disrupted
5 - 3: c. Vaporization
5 - 4: d. Gas to liquid
