Two systems are said to be in thermal contact if they can exchange heat via heat transfer irrespective of whether or not they actually do. Which of the following statements about thermal contact and thermal equilibrium is NOT true? Two objects can be in thermal equilibrium even if they are not in thermal contact with each other. Heat may be transferred between two objects when they are in thermal contact. For energy to be transferred between two objects they have to be in thermal contact. Thermal contact between two objects allows energy to be transferred without the use of macroscopic work. The fact that one object feels cold, while a second object does not feel as cold does not imply that these two objects are not in thermal equilibrium.
