Problem

A textbook draft contains the following explanation of why a metal spoon feels colder than a wooden spoon when both are at room temperature: "The wooden spoon is warmer because wood retains heat better, whereas the metal spoon absorbs cold from the surroundings, making it feel cooler to the touch." Your editor asks you to improve the explanation so that it is scientifically sound. (a) Identify two conceptual errors in the draft explanation. (b) Rewrite the explanation in one or two well-structured sentences that correct the errors while accurately describing the energy transfer that occurs when a person touches each spoon. (c) In your rewritten explanation, explicitly refer to average kinetic energy, particle collisions, and the attainment of thermal equilibrium.
