At our parent company Euroheat Australia we’ve been engineering, installing, and servicing heating, cooling, hot water, and ventilation equipment for over 29 years. WebThe rate at which heat can be dissipated (the rate it cools) is proportional to the surface area of the water (which is proportional to its size squared: r 2 ). Thus, the more water you have, the lower the ratio of surface-area to volume ( A / V ∝ r 2 / r 3 = 1 / r), and the longer it will take to cool. Aside: this is why larger mammals have ...
