onsider an exposed portion of your body (e.g., your forearm with a short-sleeved shirt) while you are sitting in a room. Identify all heat transfer processes that occur at the surface of your skin. In the interest of conserving fuel and funds, you keep the thermostat of your home/apartment at 15°C (59°F) throughout the winter months. You are able to tolerate this condition if the outside (ambient) air temperature exceeds -10°C (14°F) but feel cold if the temperature falls much below this value. Remember, the air inside is kept at 15°C (59°F). Are you imagining things?
