Similarly one may ask, what causes water to slide faster than oil?
Viscosity is the property of a liquid that describes how fast or slow it will flow; generally the thicker the liquid, the slower and more viscous it is. Peanut butter and honey are more viscous than motor oil and water.
Beside above, why does water flow fast? Water always flows downhill because of gravity. The speed water travels at depends on the amount of force working on it. When water is poured into a funnel, the wide part (cup) of the funnel will fill up quickly. That is because water can move faster in the wide area but slows down when it hits the narrow neck.
Herein, does oil cool faster than water?
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. The water is also losing heat by evaporation, as described in one of our answers on "evaporative cooling". The oils probably will evaporate much more slowly.
Which one cools faster water or liquid and why?
Water has a HUGE heat capacity. The amount of ENERGY required to bring it up to 45 degrees is MUCH higher than MOST liquids at these temperatures. So…the amount of HEAT that it would need to EXPEL…is far more…and it would take longer to cool as well.
