4. A thermometer is a device used to measure
the temperature (temperature), or a change in
temperature. The term comes from the Latin

thermometer is diverse, the most commonly
used is the mercury thermometer.

6. • prepare tools and materials

7. • mix alcohol and dyes and pour the liquid into
the bottle

8. glass pipette tip cap with plasticine

9. • adjust the tip of a glass pipette with a tip
thermometer for temperature ruler members

10. •insert the glass pipette
into the bottle until the
tip of a glass pipette on
the surface of the alcohol
•shut up the bottle with
clay or the like and make
sure there is no gap for
air exit and entry

11. o to know the exact temperature, leave the
thermometer in for one night
o to test the thermometer, insert the
thermometer into the bowl of hot water has
been filled or partially swollen thermometer
with a towel that has been soaked in hot
water

12. o simple thermometer shortage :
1. Response is slow (it takes time to raise the
volume of fluid).
2. The accuracy is relatively less, because the
minimum scale display usually only 2 Celsius.
3. difficult to use for large-scale systems, such as to
process at the factory.

13. 1. The thermometer is a device used to
measure the temperature (temperature), or a
change in temperature.
2. The solution will expand when heated.
