Ammonia dissolves better in motor oil than in vegetable oil because motor oil is more immiscible than vegetable oil. Also, motor oil molecules are more non-polar than vegetable oil.


Why cooling oil is used in transformers?

The oil in a transformer has two functions: Oil is a better electrical insulator than air is, so high voltage parts can be placed closer together, saving space and materials. Also, oil is more efficient at cooling the transformer. The oil circulates inside the transformer, removing heat from the internal core and transferring it to the cooling radiators or the surface. In small transformers, this occurs naturally, by convective currents. In large transformers, there are thermostatically controlled pumps to assist this cooling cycle.
