why the specific heat capasity of water is different in each substance?

Answer 1

The specific heat capacity of a solid or liquid is defined as the heat required to raise unit mass of substance by one degree of temperature.

To raise one gram of ice 1 degree C requires much more energy (ie. heat) than 1 gram liquid water since the bonds of the solid ice require more energy to break apart (crystal structure vs. fluid H-bonds).

Answer 2

Why are you trying to make my brain work so early in the morning? When you mix water with an another substance it forms a solution. Solutions no longer retain the same boiling point or freezing point of regular water.
