Question

1. describe the process of freezing in terms of molecular motion and temperature change.

freezing is molecules breaking apart into individual atoms as the temperature decreases.
freezing is molecules maintaining same kinetic energy their arrangement is rando as temperature decreases.
freezing is molecules gaining kinetic energy moving rapidly as the temperature decreases.
freezing is molecules losing kinetic energy, temperature decreases, forming structures.

1. freezing is the opposite of which phase change?

melting
condensation
deposition
sublimation

Question 5

To determine the correct description of freezing:

• Freezing is a phase change from liquid to solid. As temperature decreases, molecules lose kinetic energy (move slower). They then form ordered structures (solid lattice).
• The first option is wrong (freezing doesn't break molecules into atoms).
• The second option is wrong (kinetic energy decreases, and arrangement becomes ordered, not random).
• The third option is wrong (molecules lose, not gain, kinetic energy as temperature decreases).
• The fourth option correctly states molecules lose kinetic energy, temperature decreases, and form structures.

• Freezing is liquid to solid. Melting is solid to liquid—these are reverse processes (opposite phase changes).
• Condensation is gas to liquid, deposition is gas to solid, sublimation is solid to gas. None of these are the reverse of freezing except melting.

Answer:

Freezing is molecules losing kinetic energy, temperature decreases, forming structures.
