Specific Heat capacity is the
heat required to raise the
temperature of 1 kg of a substance by 1
oC (or one degree Kelvin). The
SI units of measurement for this are Jg
-1K
-1.
Factors that influence heat capacity measurements:
- The heat of the substance. For example, measure the heat capacity of water produces different results if you start at 20oC, or 60oC.
- Inter-molecular forces. If a substance has relatively strong intermolecular forces (such ashydrogen bonding in water), then the heat capacity is liable to be higher. In the case of solids this does not apply.
Heat capacity can be measured using Calorimetry
