Do you think these thermometers will give exactly the same reading at a temperature of, say, 60°C? Explain.
Understand the Problem
The question asks whether an alcohol thermometer and a mercury thermometer will give the same reading at 60°C, given that both are calibrated to read 0°C at the ice point and 100°C at the steam point. The discussion explains the importance of thermal expansion properties of the fluids used in the thermometers.
Answer
The readings might differ due to different expansion coefficients.
The readings might differ because alcohol and mercury have different thermal expansion coefficients, impacting their expansion at 60°C.
Answer for screen readers
The readings might differ because alcohol and mercury have different thermal expansion coefficients, impacting their expansion at 60°C.
More Information
Alcohol and mercury thermometers might not read the same temperature at 60°C because their different thermal expansion coefficients cause variable expansion rates.
Tips
Assuming both thermometers behave identically disregards the physical property differences affecting their readings.
