why the specific heat capasity of water is different when it is liquid solid or gas?

Answer 1

Because gas the molocules are all over the place solid the molocules are confined and liquid the molocules can move around and take the shape of its container.

Answer 2

Because of there are different density, entropy and enthalpy value in liquid, solid and gas state of water. Heat energy arises, due to the number of atoms or molecules that are vibrating. If a substance has a lighter molar mass,(Low density) then each gram of it has more atoms or molecules available to store heat energy . At the constant pressure, specific heat capacity of water Cp(L)(liquid form) is larger than (Ice)solid form,Cp(s).

Heat capacity is the measure of the heat energy required to raise the temperature of one gram of a substance by one kelvin.
specific heat capacities of water:
gas (100 °C) 2.080 (J g−1 K−1)
liquid (25 °C) 4.1813 (J g−1 K−1)
solid (0 °C) 2.114 (J g−1 K−1)

Answer 3

Mainly density. Most dense is liquid water with a heat capacity of 1 cal/deg-g. Ice is second densest (ice floats on water) with a heat capacity of 0.63. Lest dense is steam. I don't remember heat capacities of steam at various temperatures. Heat capacity involves units of grams, and there are fewer grams per mL.

Answer 4

water has differerent S.H.C. in the different forms due to the difference in the properties of water in each form like the degree of freedom and hydrogen bonds

Answer 5

TEMPERATURE CONVERSION!
