... The specific heat of water is 1 calorie/gram °C = 4.186 joule/gram °C which is higher than any other common substance. As a result, water plays a very important role in temperature regulation. The specific heat per gram for water is much higher than that for a metal, as described in the water-metal ...

... Specific Heats and Changes in Internal Energy and Enthalpy for Ideal Gases Before the first law of thermodynamics can be applied to systems, ways to calculate the change in internal energy of the substance enclosed by the system boundary must be determined. For real substances like water, the prope ...

... Heat and work are best thought of as processes by which energy is exchanged, rather than as energy itself. That is, heat “exists” only when it is flowing, work “exists” only when it is being done. When two bodies are placed in thermal contact and energy flows from the warmer body to the cooler one, ...

... Since water is in a liquid form at the reference temperature of 25 °C for pressures higher than 0.032 bar, the Cp functions for steam follow the saturated steam curve below the boiling point. This means that the pressure is not kept constant below this point and thus the pressure value in the specie ...
