Question

question 3. during a flight, why might passengers feel colder near the airplane windows compared to the middle of the cabin during flight? a. radiation from the sun warms the center of the cabin more effectively. b. cold air entering through the door creates drafts. c. the windows, being cooler due to external temperatures, conduct heat away from passengers. d. convection currents are stronger in the center of the cabin.

Explanation:

When an airplane is flying, the outside temperature is very low. The windows are in direct contact with the cold external environment. Heat transfer occurs through conduction. The cooler windows conduct heat away from the passengers near them. Option A is incorrect as the sun's radiation is not the main factor here. Option B is wrong because cold air entering through the door is not the reason for the temperature difference near the windows. Option D is also incorrect as convection currents are not the main cause of the temperature difference near the windows compared to the middle of the cabin.

Answer:

C. The windows, being cooler due to external temperatures, conduct heat away from passengers.
