In a water-in-oil emulsion, which are the internal and external phases?

Explanation:
In a water-in-oil emulsion, water forms the droplets that are dispersed throughout a continuous oil phase. The term “internal” means the phase present as droplets inside the other phase, while “external” is the surrounding continuous medium. So, the internal phase is water and the external phase is oil. This is the opposite of an oil-in-water emulsion, where oil droplets are dispersed in water.
