What is the specific heat capacity of water in J/(kg·K)?

The specific heat capacity of water is a fundamental property that indicates how much heat energy is required to raise the temperature of one kilogram of water by one degree Kelvin (or one degree Celsius). The accepted value for the specific heat capacity of water is approximately 4184 J/(kg·K). This value is significant in many engineering and scientific calculations, particularly those involving heat transfer, thermodynamics, and fluid dynamics.

Water's high specific heat capacity means it can absorb and store large amounts of thermal energy without experiencing a significant change in temperature. This property is crucial in various applications, including climate regulation, heating and cooling systems, and in processes where temperature stability is essential.

The other values listed do not correspond to the standard specific heat capacity of water. Specific heat capacities can vary for different substances or under different conditions, but 4184 J/(kg·K) is widely recognized as the value for liquid water at room temperature and standard pressure.
