    Thermal conductivity is how quickly heat moves through the element as a medium. You would want low conductivity when insulating your base, but high conductivity when transferring heat to be deleted. Heat capacity is how much energy is required to raise the temperature of the element by 1 degree. Some elements like water need lots of energy to be heated, others like metals, need much less.
