Answer:
360 J/kg/°C
Explanation:
Heat lost by metal = heat gained by water
-m₁ C₁ (T − T₁) = m₂ C₂ (T − T₂)
-(0.059 kg) C (27.4°C − 221°C) = (0.409 kg) (4186 J/kg/°C) (27.4°C − 25°C)
(11.4 kg°C) C = 4109 J
C = 360 J/kg/°C
Answer:
After sufficient thickness of ice is formed it prevents further loss of heat from the bottom layers of water. This is why fishes and other aquatic animals and plants can survive in ponds and other water bodies even when the atmospheric temperature reaches or is well below 0 degrees.The anomalous expansion of water helps preserve aquatic life during very cold weather. When temperature falls, the top layer of water in a pond contracts becomes denser and sinks to the bottom. ... Thus, even though the upper layer are frozen, the water near the bottom is at 4°C and the fishes can survive in it easily.
In theory, yes. The 2 problems are the materials used for clinical thermometers, & the temperature capacity of the clinical thermometer. If anything, change the material & extend the measurement threshold. At that point, it wouldn´t be used for clinical garbage anymore.
