The specific heat capacity of water is approximately 4.186 joules per gram-degree Celsius (J/g°C). This means that it takes approximately 4.186 joules of heat energy to raise the temperature of 1 gram of water by 1 degree Celsius.
It's worth noting that the specific heat capacity of water can vary slightly with temperature, but the value mentioned above is a commonly used approximation that holds well within a typical temperature range.
