Answer 1

Explanation:

Aerosols that are soluble in water (e.g. salt or sulphuric acid) can induce condensation in unsaturated air, e.g. salt nuclei can induce it at a relative humidity of less than 80%. The size of nuclei may be from 0.001 μm to more than 10 μm (i.e. ‘giant’ nuclei such as particles of sea-salt)
