Why is the specific heat of water higher than water vapor?

That’s why water is able to flow past itself, but also bond together—it’s constantly forming and breaking these bonds. These bonds are also why liquid water has a high specific heat. Because of this, it takes more energy to heat water than it does other substances.

Why is the specific latent heat of vaporization of water much larger than its specific heat capacity?

The energy required to completely separate the molecules, moving from liquid to gas, is much greater that if you were just to reduce their separation, solid to liquid. Hence the reason why the latent heat of vaporization is greater that the latent heat of fusion.

Why do solids have a lower specific heat capacity than liquids?

This is because solids expand slightly on heating. The atoms get farther apart and thus increase in potential as well as vibrational energy. Solids which contain molecules rather than atoms have much higher heat capacities than 3R.

What is the specific heat of water vapor?

1.996 kJ/kgK
Specific heat water vapor: 1.996 kJ/kgK =0.4767 Btu(IT)/(lbm °F) or kcal/(kg K)

Why latent heat of vaporization is always greater than latent heat of fusion?

The latent heat of vaporization is higher than the latent heat of fusion since gas molecules have the largest intermolecular space and the force of attraction between the molecules is almost negligible. Therefore, more energy is required to convert liquid to gas.

Why the heat of vaporization is higher in value as compared to the heat of fusion of different substances?

Notice that for all substances, the heat of vaporization is substantially higher than the heat of fusion. Much more energy is required to change the state from a liquid to a gas than from a solid to a liquid. This is because of the large separation of the particles in the gas state.

Why is specific heat capacity of ice less than water?

When matter is heated, the kinetic energy of its particles increase, and the intermolecular bonds are broken. Ice has a covalent molecular structure, which make its intermolecular bonds easier to break than that of water. Therefore, the specific heat capacity of ice is lower than that of water.
