Between MERCURY THERMOMETER and

ALCOHOL THERMOMETER from the ADVANTAGES

and DISADVANTAGES are :

ADVANTAGES :

1.CHEAP

2.DURABLE

3.ACCURATE

4.EASILY CALIBRATE

DISADVANTAGES :1.Display is harder to read2.does not work below -39ºC (Hg freezing pount)3.cannot be used for thermograph4.slow response5.Fragile6.mercury vapour is poisonous

ADVANTAGES :

1.lower freezing point (-114

ºC) 2.larger coefficient of

expansion

3.less hazardous

DISADVANTAGES :1.less durable (alcohol evaporates) 2.alcohol can polymerise3.fluid loss by evaporation hard to avoid4.lower boiling point (60 ºC)

DEFINITION Of CLINICAL THERMOMETER

thermometer used to measure body temperature, especially a small glass thermometer designed with a narrowing above the bulb so that the mercury column stays in position when the instrument is removed from the body.

A thermometer having a graduated glass tube with a bulb containing a liquid, typically mercury or colored alcohol, that expands and rises in the tube as the temperature increases.
