a) Clinic thermometer
b) Wall thermometer
c) Six- Bellani Maximum and Minimum
thermometer
A. CLINIC THERMOMETER
•The scale of the themometer
is designed from 35°C until
42°C
•It ussually used to measure a
human body temperature
B. WALL THERMOMETER
It has two measurement
scales, are Celcius and

and minimum temperature
ADVANTAGE OF ALCOHOL AND
MERCURY THERMOMETER
Advantage of:
a) Alcohol thermometer
- alcohol is cheaper than mercury
- it can measure a low temperature (130°), because its freezing point is
low
- it can measure the temperature precisely, because it has large expansion
coefficient
- the expansion is regular
b) Mercury thermometer
- this is visible, because its colour is silvery shining
- its expansion is regular
- it doesn’t make wet the wall of its place
- it can measure a high temperature (360°), because its boiling point is
high
- it can measure the temperature quickly and precisely
-mercury can measure low temperature (-40°)
DISADVANTAGE OF ALCOHOL
AND MERCURY THERMOMETER
Disadvantage of:
a) Alcohol thermometer
-it cannot measure a high temperature, because its bolling point is low (78°)
-it makes wet the wall of its place
-it is colourless so it must be given dyestuff in order to be visible
b) Mercury thermometer
-it cannot measure very low temperature, because its freezing point is high
(-40°C)
-mercury is poisonous, so its harmful if its tube is broken
-its prices is very expensive
