 Mar 7 awarded Enlightened Mar 7 awarded Nice Answer Mar 3 comment Which will keep my food colder longer, draining the melted ice water, or leaving it in the cooler? Yes, but that's irrelevant to what I'm saying. The rate of heat flowing into the cooler is determined solely by the temperature difference between the inside and the outside; water's higher thermal conductivity just means the temperature inside equalizes more quickly. Because water has a higher specific heat, it will take more heat energy to warm the water's temperature. Since the rate of heat flowing in is the same, the water's temperature, and therefore the fish's, will rise more slowly. Mar 2 awarded Pundit Mar 1 comment Which will keep my food colder longer, draining the melted ice water, or leaving it in the cooler? Heat only flows back into the fish if there is a temperature difference. With a fish in water at the same temperature, there is no heat flow back in from the water directly. The heat flows into the cooler (fish or fish+water) at a rate dependent on the temperature difference (inside vs. outside). The temperature change due to heat flow is dependent on how much there is to heat. Thus, the heat flowing into a cooler takes much longer to heat both the fish and water than just the fish. Mar 1 comment Which will keep my food colder longer, draining the melted ice water, or leaving it in the cooler? The problem with this logic is that it takes less heat energy to re-warm a fish than the fish and several gallons of water. So if the heat is flowing in at the same rate with and without the water, keeping the water keeps the whole system cool longer.
