Does oil help water boil faster?

If a layer of vegetable oil floats on top, it prevents the evaporation from happening, and so the water retains a larger fraction of the heat given to it by the stove and comes more quickly to a boil.

Does water boil slower with oil?

A: Actually, the water can evaporate at lower temperatures than 100°C, just as it could with no oil. However, the oil layer can slow the evaporation dramatically. If the water is heated to boiling, with big bubbles of vapor popping up from inside the liquid, the oil will be less effective in slowing the evaporation.

What cools faster water or oil?

Since the water has a higher specific heat than most oils, it would have to lose more heat to cool down, and you would then expect it to cool slower. However, there are other complications. The water is also losing heat by evaporation, as described in one of our answers on “evaporative cooling”.
