Answer the following statement(s) true (T) or false (F)
1. One of the most important properties of water relevant to its use in hydronic systems is specific heat. 2. If the material changes phase while absorbing heat, its temperature will change 3. The specific heat of water is high in comparison to other common materials. In fact, water has one of the highest specific heats of any known material. 4. The difference in heat capacity of water versus that of air is the single greatest advantage of using water rather than air to convey heat. 5. The density of water is not dependent on temperature.
