A physics question for everyone to try
◗ Through Thick and Thin
Challenge: A thin metal plate is suspended in the air. One side of the plate is exposed to direct sunlight. The temperature of the exposed surface of the plate is 360 K. The temperature of the opposite surface is 340 K. The air temperature is 300 K. What would be the temperatures of the surfaces of the plate made of the same metal that is twice as thick? The air temperature remains the same.
