Specific Heat Capacity & WaterFormula & Detailed,

11/02/2018· The specific heat capacity of water vapour at room temperature is also higher than most other materials. For water vapour at room temperature and pressure, the value of specific heat capacity (Cp) is approximately 1.9 J/g°C. As with most liquids, the temperature of water increases as it absorbs heat and decreases as it releases heat. However, the temperature of liquid waterfalls & rises more,

What Is the Specific Heat of Water? How Is It Special?

The specific heat of water is quite a bit higher than many other common substances. For example, the specific heat of iron is 449 J/kg°C, sand is 830 J/kg°C, and oak timber is 2400 J/kg°C. That’s because water, comprised of two hydrogen atoms and one oxygen atom, is electronegative. An electronegative atom is more likely to draw electrons to itself, because one side of the atom will have,
