What is the specific heat of water in steam?
Heat Capacities for Some Select Substances
| Substance | specific heat capacity Cp,s (J/g °C) | molar heat capacity Cp,m (J/mol °C) |
|---|---|---|
| titanium | 0.523 | 26.06 |
| water (ice, O°C) | 2.09 | 37.66 |

Why is the specific heat of water higher than ice and steam?
In ice, the water molecules are pushed farther apart than they are in liquid water. That means water expands when it freezes. That’s why specific heat of water and ice are different. When matter is heated, the kinetic energy of its particles increase, and the intermolecular bonds are broken.
What is the specific heat of water vapor in J GC?
Because there are 4.184 joules in a calorie, the specific heat of water is 4.184 J/g-K. The ease with which a substance gains or loses heat can also be described in terms of its molar heat capacity, which is the heat required to raise the temperature of one mole of the substance by either 1oC or 1 K.
What is the specific heat capacity of ice water and steam?
2.108 kJ/kgK
The specific heat capacity, or the amount of heat needed to raise the temperature of a specific substance in a specific form one degree Celsius, for water is 4.187 kJ/kgK, for ice 2.108 kJ/kgK, and for water vapor (steam) 1.996 kJ/kgK.
Why does ice and water have different specific heat capacity?
As a liquid, water has more directions to move and to absorb the heat applied to it. There is more surface area that needs to be heated for the overall temperature to increase. However, with ice, the surface area doesn’t change due to its more rigid structure.
How do you find the specific heat capacity of a steam?
The heat absorbed is calculated by multiplying the moles of water by the molar heat of vaporization. 5. Steam is heated from 100oC to 140oC. The heat absorbed is calculated by using the specific heat of steam and the equation ΔH=cp×m×ΔT.
What is the specific heat value of water?
4.186 J/g°C
Water has a specific heat capacity of 4.186 J/g°C, meaning that it requires 4.186 J of energy (1 calorie) to heat a gram by one degree.
How do you find the specific heat of water vapor?
Calculate specific heat as c = Q / (mΔT) . In our example, it will be equal to c = -63,000 J / (5 kg * -3 K) = 4,200 J/(kg. K) . This is the typical heat capacity of water.
Why is the specific heat of steam less than water?
Considering the molecular arrangement of liquids and vapours, it is logical that the density of steam is much less than that of water, because the steam molecules are further apart from one another. The space immediately above the water surface thus becomes filled with less dense steam molecules.
