1. temperature seventh grade

2. temperature ≠ heat Heat: a form of flowing energy. Temperature: degree / level of heat energy of an object. Low temperature: the object's heat energy level = low High temperature: the object's heat energy level = high Temperature is the condition of hot and cold an object

3. SUHU ≠ PANAS Panas : s uatu bentuk energi yang mengalir . Suhu : derajat/tingkat energi panas suatu benda . Suhu rendah : tingkat energi panas benda = rendah Suhu tinggi : tingkat energi panas benda = tinggi Suhu adalah kondisi panas atau dinginnya suatu benda

4. Thermos (Greek) means heat, while meter means measure. So thermometer is temperature measuring instrument Thermometer

5. Termos (Yunani) berarti panas , sedangkan meter berarti mengukur. Jadi termometer adalah alat ukur suhu TERMOMETER

6. Thermometric property of a substance is the volume of a substance changes when it is heated or cooled. Heat energy causes liquid molecules to move apart the distance between the molecules is widened the volume increases, the mass of the substance stays the same. thermometer working principle

7. Sifat termmetri suatu zat adalah perubahan volume suatu zat bila dipanaskan atau didinginkan Energi panas menyebabkan molekul zat cair bergerak terpisah jarak antar molekul semakin lebar volumenya naik , massa zat tetap Prinsip kerja termometer

8. Liquid filled thermometer various types of thermometers clinical thermometer maximum-minimum Six Bellani thermometer room thermometer laboratory thermometer

9. Termometer zat cair jenis termometer Termometer klinis Termometer maximum-minimum Six Bellani Termometer ruang Termometer laboratorium

10. solid filled thermometer various types of thermometers bimetal thermometer resistance thermometer thermocouple thermometer

11. Termometer zat padat JENIS TERMOMETER Termometer bimetal Termometer hambatan Termometer termokopel

12. gas filled thermometer various types of thermometers

13. Termometer zat gas JENIS TERMOMETER

14. Optical Thermometer various types of thermometers pyrometer thermometer infrared thermometer

15. Termometer optik JENIS TERMOMETER Termometer pirometer Termometer inframerah

16. the thermometer filling liquid Mercury Alcohol Does not wet the walls of the capillary tube, easy to see because it is shiny. Quickly take heat from an object that is being measured. The temperature range is quite wide. Freezing point : -40 degrees celcius and boiling point : 36 degrees celcius. The volume of mercury changes regularly. The price is cheap. More precisely, for a small increase in temperature alcohol undergoes a large change in volume Can measure very low temperatures, because the freezing point of alcohol -130 degrees celcius. Wet glass walls Low boiling point 78 degrees celcius Alcohol is colorless, it needs a dye to be visible.

17. ZAT CAIR PENGISI TERMOMETER Raksa A lkohol Tidak membasahi dinding pipa kapiler , mudah terlihat karena mengkilat . Cepat menyerap kalor dari suatu benda yang sedang diukur . Kisaran suhunya cukup lebar . Titik beku : -40 derajat celcius dan titik didih : 360 derajat celcius . Volume raksa berubah secara teratur . Harganya murah . Lebih tepat , dengan sedikit peningkatan suhu,alkohol mengalami perubahan volume yang besar. Dapat mengukur suhu rendah , karena titik beku alkohol -130 derajat celcius. Membasahi dinding kaca. Titik didihnya rendah, yaitu 78 derajat celcius Alkohol tidak berwarna , sehingga perlu pewarna agar terlihat .

18. Because water has anomalous properties. Most substances expand when heated. However, at a temperature of 0-40C, water actually shrinks. Why isn't water used as a thermometer filler?

19. Karena air memiliki sifat anomali. Kebanyakan zat memuai jika dipanaskan. Namun pada suhu 0 – 40 derajat celcius, air justru menyusut. Mengapa bukan air sebagai zat pengisi termometer ?

20. Thermometer scale   Keterangan : ta : titik tetap atas tb : titik tetap bawah tx : skala yang diketahui ty : skala yang ditanyakan

21. temperature conversion scale

22. temperature conversion scale

23. The QuiZ 1. The condition of hot and cold an object is ... Heat Temperature Energy

24. The QuiZ 2. Which one is the liquid fillled thermometer A B C

25. The QuiZ 3. Which one is the solid fillled thermometer? A B C

26. The QuiZ 4. Which one is the gas filled thermometer? A B C

27. The QuiZ 5. What is the negative impact of alcohol as a thermometer filler? A B C Wet the glass wall The glass wall look shiny The price is cheap

28. The QuiZ 6. What is the positive impact of mercury as a thermometer filler? A B C Wet the glass wall The price is cheap Easy to see because shiny

29. The question Nita was measuring the temperature of the hot tea she had just made. The temperature of the hot tea is 50 degrees Celsius . What is this temperature if expressed in : Reamur Scale Fahrenheit Scale Kelvin Scale 7. 8. Determine the X scale!

30. The answer 7. 8.
