In the winter, Keiko and Jamal are standing beside a metal pole and a wooden post. Keiko places her hand on the metal pole and Jamal places his hand on the wooden post. Both the pole and the post are the same temperature. Who is likely to feel colder and why? Respond very briefly.
Keiko is likely to feel colder than Jamal because metal conducts heat more effectively than wood. When Keiko places her hand on the metal pole, heat from her hand is conducted away to the pole more quickly than heat is conducted away from Jamal's hand by the wooden post. This rapid transfer of heat from Keiko's hand to the pole makes her perceive the pole as being colder, even though both the pole and the post are at the same temperature.
