“TEMPERATURE AND ITS MEASUREMENT” “SUHU DAN PENGUKURANNYA”
The Definition of Temperature Pengertian suhu • Temperature is the hotness or coldess degree of an object • Suhu adalah derajat panas atau dinginnya suatu benda
Thermometer Thermos panas Thermometer Meter pengukur Etymologically (Secara Bahasa) : Thermometer is a device used to measure the temperature Termometer adalah alat yang digunakan untuk mengukur suhu
• Thermometer is made according to the properties of a substance which can change if it undergoes the change of temperature • Termometer dibuat berdasarkan sifat-sifat pada suatu zat yang dapat berubah bila mengalami perubahan suhu • The changes are (Perubahan – perubahan itu adalah) : 1. Chemical changes (Perubahan kimia) 2. Physical changes (Perubahan fisika)
• Chemical Changes (Perubahan Kimia) example : Heated Woods (dipanaskan) (kayu) Charcoal (arang) • Physical Changes (Perubahan Fisika) 1. The change of phase (Perubahan wujud) example : Heated ice (dipanaskan) water melted (mencair) (es) (air)
2. The change in volume (Perubahan Volum) example : Dipped into the air in a balloon the air will hot water expand, the balloon develops (udara dalam balon Direndam dalam udaranya air panas akan memuai, sehingga balon mengembang) 3. The change of electic conductivity (Perubahan daya hantar listrik) example : an electric conductor the electric Heated conductivity decrease (dipanaskan)
dipanaskan (kawat penghantar listrik daya hantar listriknya berkurang 4. The change of colour (Perubahan warna) example : Heated iron dipanaskan the colour become red (besi) (warnanya menjadi merah)
Alcohol thermometer Termometer Alkohol
Mercury thermometer Termometer Merkuri
Alcohol The Superiorities (Kelebihan) The weakness (Kelemahan) Can measure low temperature == > the freezing point is low (115 o. C) ( dapat mengukur suhu yang rendah ==> titik bekunya rendah (-115 o. C) Can’t measure high temperature == > the boiling point is low (78 o. C) ( tidak dapat mengukur suhu yang tinggi == > titik didihnya rendah (78 o. C) Can measure the temperature precisely == > has large expansion coefficient (dapat mengukur suhu dengan teliti == > memiliki koefisien muai yang besar) Makes wet the wall its place (membasahi dinding tempatnya) The expansion is regular (pemuaiannya teratur) Colourless (tidak berwarna)
Mercury The Superiorities (Kelebihan) The Weakness (Kelemahan) Visible == > its colour is silvery shining (mudah dilihat == > warnanya mengkilap seperti perak Can’t measure very low temperature == > its freezing point is high (-40 o. C) (tidak dapat mengukur suhu yang rendah == > titik bekunya tinggi (-40 o. C) Can measure high temperature == > its boiling point is high (356, 9 o. C) (dapat mengukur suhu yang tinggi == > titik didihnya tinggi (356, 9 o. C) Poisonous ==> harmful if its tube is broken (Beracun == > berbahaya jika tabungnya pecah) It doesn’t make wet the wall of its place (tidak membasahi dinding tempatnya) The price is very expensive (harganya sangat mahal) Can measure the temperature quickly and precisely (dapat mengukur suhu dengan cepat dan tepat) The expansion is regular (pemuaiannya teratur)
Temperature scale Skala Temperatur
The relationship between the four thermometer scale Hubungan antara keempat skala termometer
The calculation becomes perhitungannya menjadi: Pembanding Celcius (C) Kelvin (K) Reamur (R) Fahrenheit (F) Yang dicari Celsius (C) X (K – 273) 5/4 R 5/9 (F – 32) (C + 273) X 5/4 R +273 5/9 (F – 32) + 273 Reamur (R) 4/5 C 4/5 (K – 273) X 4/9 (F – 32) Fahrenheit (F) 9/5 C + 32 9/5 (K – 273) + 32 9/4 R +32 X Kelvin (K)
Kinds of Thermometer Macam-macam Termometer • Clinic thermometer (termometer klinis) usually used to measure a human body temperature (biasanya digunakan untuk mengukur suhu tubuh manusia)
• Wall thermometer (Termometer dinding) used to measure a room temperature (digunakan untuk mengukur suhu ruangan) • Six – Bellani Maximum and Minimum thermometer (Termometer Maksimum dan minimum Six – Bellani) used to measure a maximum temperature, mainly inside the greenhouse (digunakan untuk mengukur suhu maksimum terutama di dalam rumah kaca)
