Concept:A thermometer measures temperature using a specific thermometric property that changes predictably with temperature.
Explanation:The liquid-in-glass thermometer uses a liquid, such as mercury or coloured alcohol.
As temperature increases, the liquid expands.
As temperature decreases, the liquid contracts.
This expansion and contraction cause the volume of the liquid to change.
The height of the liquid column shows this volume change, which is then read as temperature.
Therefore, the thermometric property is change in volume with temperature.
Answer:D. Liquid-in-glass thermometer.
