Problem
When we touch an object, thermal energy is transferred between the object and our fingers. Suppose that you are sitting on a chair in a classroom. The chair has metal legs and a soft fabric seat. Both the legs of the chair and the soft fabric seat are at the same temperature—the temperature of your classroom.
(a) When you touch the fabric seat of the chair, will it feel hot, cold, or neither? Explain your answer by referring to what you know about conduction.
(b) When you touch the metal legs of the chair, will they feel hot, cold, or neither? Explain your answer by referring to what you know about conduction.
