A liquid-in-glass thermometer consists of a bulb containing a liquid which expands into a thin capillary tube. The liquid in the thermometer is replaced by the same volume of a different liquid that expands more for the same temperature rise. The length of the capillary tube remains the same. How does the new thermometer compare with the old thermometer?
