Most recent answer: 06/08/2016
Cooling in water is faster than cooling in air. This is due to larger specific heat of water or larger heat transfer coefficient. Which one is the predominant factor?

You can write the thermal conductivity as the product of two factors: the heat capacity per volume and the thermal diffusion coefficient. Water has a much higher thermal conductivity than air precisely because it has much more heat capacity per volume.
