Consider a stainless steel spoon (k= 8.7 Btu/hftF) partially immersed in boiling water at 200F in a kitchen at 75F. The handle of the spoon has a cross section of 0.08 in 0.5 in and extends 7 in in the air from the free surface of the water. The heat transfer coefficient at the exposed surfaces of the spoon handle is 3 Btu/hft²F.

NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part.

A spoon is placed inside the container, such that the distance of the water level from the top end of the handle of the spoon is 7 meters. T sub air is indicated in the region outside the container.
