What term describes the absence of caloric energy in a material?

The term that describes the absence of caloric energy in a material is "frigoric." This concept stems from historical theories in thermodynamics that referred to the hypothetical substance called caloric, which was once thought to be the fluid responsible for heat. In this context, frigoric is used to denote a state where there is no caloric energy present, effectively implying a lack of thermal energy or heat within the material.

Thus, frigoric signifies a condition where a substance is devoid of that thermal energy, leading to lower temperatures. This term helps to illustrate the contrast between heat presence (caloric) and its absence (frigoric), highlighting the thermodynamic processes involved in heat transfer and energy states. Understanding terms like frigoric is crucial in thermodynamics as they provide insights into temperature, energy transfer, and the behavior of materials under different thermal conditions.
