If the air becomes cooler, some of the water vapour will condense into a liquid. What do condensation nuclei have to do with this process?

Condensation occurs only when the air is cooled to the dew point and condensation nuclei (surfaces) are available.
Basically, all a condensation nucleus is is a microscopic particle such as dust, salt or smoke. Water vapor will condense around these condensation nuclei.

Condensation takes place in presence of condensation nuclei.This is explained below.
Condensation nuclei are small particles(dust particles.salt particles,smoke,droplets of sulphuric acid etc) about which cloud droplets coalesce.Water requires a non-gaseous surface to become liquid from a vapour stage.The condensation nuclei ,above mentioned,serve this purpose in the atmosphere.So, water vapour condences over these particles to become tiny water droplets which constitute the cloud.
