For water you can check engineering tables since people already labeled water so you don't need t.. Specific Heat Capacity Table. Substance: Specific Heat Capacity at 25 o C in J/g o C: H 2 gas: 14.267: He gas: 5.300: H 2 O (l): 4.184: lithium: 3.5 The heat capacity of pure hydrogen gas at room temperature is 14.3 J/g°C, according to the CRC Handbook of Chemistry and Physics. Pure H 2 is not a big player in the Earth's climate system, though.) The high C p of water is why a watched pot never boils Specific Heat The specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius. The relationship between heat and temperature change is usually expressed in the form shown below where c is the specific heat Water has a high heat capacity because a lot of heat energy is required to break the hydrogen bonds found in a molecule of water. Because the majority of heat energy is concentrated on breaking the hydrogen bonds, the water molecule itself heats up after the bonds are broken

If the heat capacity is constant, we find that !. On the other hand, in general the heat capacity can be temperature-dependent. A general temperature-dependent empirical form for the heat capacity for ideal gases and incompressible liquids is: # $% & where #,$, , and % are substance-dependent constants and is absolute temperature Thus, the specific heat of a gallon of milk is equal to the specific heat of a quart of milk. A related quantity is called the heat capacity (C). of an object. The relation between S and C is C = (mass of obect) x (specific heat of object). A table of some common specific heats and heat capacities is given below     Specific Heat Capacity. The specific heat capacity is the amount of heat it takes to change the temperature of one gram of substance by 1°C. So, we can now compare the specific heat capacity of a substance on a per gram bases. This value also depends on the nature of the chemical bonds in the substance, and its phase Dachs, E., & Geiger, CA.(2008).
