1. THERMOMETER BY AUDI NAONI AZIZSOL CLASS 7C

2. KINDS OF THERMOMETER Many kinds of thermometer are: a)Clinic thermometer b)Wall thermometer c)Six- Bellani Maximum and Minimum thermometer

3. 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

4. B. WALL THERMOMETER It has two measurement scales, are Celcius and Fahrenheit scales It is used to measure a room temperature

5. C. SIX- BELLANI MAXIMUM AND MINIMUM THERMOMETER It is used to measure a maximum and minimum temperature

6. 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°)

7. 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
