Specific heat capacity (SHC):
The specific heat capacity is defined as the quantity of heat (J) absorbed per unit mass (kg) of the material when its temperature increases 1 K (or 1 °C), and its units are J/(kg K) or J/(kg °C). Source Basically, the higher the SHC the more heat energy need to raise the temperature in the material.
The higher this property is the better a material is as a heat buffer against temp spikes up or down.
When combined with a high conductivity material to dissipate the heat, you can make a cooling system that works very energy efficiently and with little fluctuations in the environment you are controlling the temperature for.
