Thermodynamic system is said to be in thermal contact with another system when it can exchange energy through heat. The thermal isolation is an idealisation as real systems are always in thermal contact with their environment to some related extent. When two solid bodies are in contact, a resistance to heat transfer exists between the bodies. The study of heat conduction between such bodies is called thermal contact conductance.
