Analysis of metal temperature difference differences
Thread Content
There is now a water tank containing half a tank of water. A metal object is placed vertically in the middle of it, and the area below it is heated to 40 degrees. Why isn’t the metal inside the water hot, while the metal that is outside is quite hot to the touch? Aren’t metals good conductors of heat? Why is there such a large temperature difference between the top and bottom and that in the water?
What does it mean to heat it to 40 degrees below? Is it the water at 40°C, the pot at 40°C, or the bottom part of the metal at 40°C?
What is the heat source for heating? Are it your several \"metal objects\"? Use a heating rod to heat water; of course, the heating rod is hotter than the water
It’s not just a metaphor. It’s like using liquefied gas to heat water in a pot; we turn off the heat once the temperature reaches 40 degrees
In this metal rod, does heat transfer occur directly through contact with the bottom of the pot, or is it transferred through hot water?
Does this metal rod transfer heat directly in contact with the bottom of the pot, or through hot water?
That’s normal – metals conduct heat quickly, while the heat transfer between metals and water is slower
