The metal used in clinical thermometers is mercury.
The reason as to why it is used is because :
1) It expands uniformly on heating and contracts uniformly on cooling.
2) It is sensitive to slight temperature changes.
3) It exists in liquid state despite being a metal.
4) It forms a lower meniscus compared to other thermometer liquids.
