Two liquid-in-glass thermometers have identical dimensions. One contains ethanol and the other an equal volume of mercury. Ethanol expands more than mercury for the same temperature rise. How do the sensitivity and range of the ethanol thermometer compare to those of the mercury thermometer?
Asensitivity of ethanol thermometer: greater, range of ethanol thermometer: greater
Bsensitivity of ethanol thermometer: greater, range of ethanol thermometer: smaller
Csensitivity of ethanol thermometer: smaller, range of ethanol thermometer: greater
Dsensitivity of ethanol thermometer: smaller, range of ethanol thermometer: smaller
✓ Correct answer
B: sensitivity of ethanol thermometer: greater, range of ethanol thermometer: smaller
