問 2
1 点Which row correctly identifies the changes in the separation and average speed of particles when a substance undergoes freezing?
問 3
1 点During the process of melting, a solid is heated but its temperature remains constant until all the solid has turned into a liquid. Why does the temperature not increase during this time?
問 4
1 点According to the kinetic particle theory, what happens to the average kinetic energy of the particles in a substance as its temperature increases?
問 5
1 点Which diagram represents the arrangement of particles in a liquid?
Diagram W: Particles widely spaced and moving randomly.
Diagram X: Particles close together in a regular lattice.
Diagram Y: Particles close together and touching but randomly arranged.
Diagram Z: Particles vibrating about fixed points in a pattern.

問 9
4 点The states of matter have distinct physical properties based on their particle structure.
(a) Identify which state of matter (solid, liquid, or gas) cannot easily be compressed and has a definite shape.
(b) Describe the motion of particles in:
(i) a solid
(ii) a liquid
(c) State the term used to describe the change of state from a liquid to a gas at the boiling point.

問 10
5 点The kinetic particle model describes how the arrangement and motion of particles change when a substance changes state.
(a) Compare the separation and arrangement of particles in a solid with those in a liquid.
(b) Using the kinetic particle theory, explain why the pressure of a fixed mass of gas increases when its temperature is increased at a constant volume.
(c) Name the process that occurs when a gas changes directly into a liquid.
