Question 4

A vapour passes over cool metal tubes and changes into a liquid. As this change of state happens, energy is transferred to the tubes.

Which statement explains this energy transfer?

[1]
A

Energy stored in the empty spaces between particles is released as those spaces become smaller.

B

Attractions between the particles are overcome as liquid forms, releasing energy to the metal tubes.

C

The vapour reacts with the metal tubes as liquid forms, releasing energy in a chemical change.

D

Attractions pull the particles closer together as the liquid forms, releasing energy to the metal tubes.
