  3. Temperature • Temperature is the degree of heat an object is measured using a thermometer. In everyday life we use a thermometer liquid and typically use mercury or alcohol. Determining equivalence scale thermometer

  4. MacammacamTermometer • Termometer air raksa Air raksamembekupada -40° C danmendidihpada 360° , makatermometer air raksahanyadapatdipakaiuntukmengukursuhu-suhudiantara interval tersebut. • Termometeralkohol Untuksuhu-suhulebihrendahdapatdipakai alcohol (Titikbeku - 130° C ) danpentana (Titikbeku - 200° C )sebagaizatcairnya. • Termoelemen Alatinibekerjaatasdasarnyatimbulnyagaya gerak listrikdariduabuahsambunganlogambilasambungantersebutberubahsuhunya.

  5. Kinds of thermometer • Mercury thermometer Mercury freezes at -40 ° C and boils at 360 °, then the mercury thermometers can only be used to measure temperatures between these intervals. • Alcohol thermometer For temperatures lower alcohol can be used (freezing point - 130 ° C) and pentane (freezing point - 200 ° C) as a liquid substance. • Termoelemen It works on basically the emergence of electromotive force of the two metal connections when the connection is changing its temperature.

  7. Pirometer Optics This tool can be used to set a very high temperature. • Maximum thermometer Thermometer is used to determine the temperature of the highest or lowest in a certain time. • Thermostat This tool is used to obtain a fixed temperature in a room. • Thermometer differential. Used to determine the temperature difference between two adjacent places.

  8. Kalor • SifatTermalzatialah : bahwasetiapzat yang menerimaataupunmelepaskankalor,makazattersebutakanmengalami : -Perubahansuhu / temperature / derajatpanas -Perubahanpanjangataupunperubahan volume zattersebut -Perubahanwujud

  9. Heat • Thermal properties of matter is this: that any substance that receive or release the heat, then the substance will experience: • Changes in temperature / temperature / degree of heat • Change in length or volume changes in substance • Change form

  10. KalorJenis c = kalorjenis (kal/gr° C,J/kg° K) Q = jumlahkalor (kal,Joule) m = massa (kg) = perubahansuhu (°C,°K)

  11. Heat Type • c = Specific heat of (cal / g ° C, J / kg ° K) • Q = amount of heat (cal, joule) • m = mass (kg) • = Change in temperature (° C, ° K)

  12. Kapasitaskalor • C = kapasitaskalor (panas) (kal/°C,J/ ° K)

  13. Heat capacity C = Specific heat capacity (heat) (cal / ° C, J / ° K)

  14. KalorLaten • L = kalorlaten (kal/gr,J/kg) • m= massa yang berubahwujud (kg) • Q = kalor (panas)

  15. Latent Heat L = Laten head (kal/gr,J/kg) m= mass change shape(kg) Q = Head (hot)

  16. Azaz Black • Q dilepasA = Q diserapB

  17. Azaz Black • If the object A release heat on body B then: • QdetachedA = QreserveB

  18. Kesetaraanantarasatuankalordansatuanenergi. • Kesetaraansatuankalordanenergimekanikinimakaditentukanoleh “PERCOBAAN JOULE” Atau 1 kalori = 4,2 joule 1 joule = 0,24 kal Hargaperbandingandiatasdisebut “TARA KALOR MAGNETIK”

  19. Equality between the unit and the unit of heat energy. • Equality unit of heat and mechanical energy is then determined by the "EXPERIMENT Joule" or • Price comparison above is called "MAGNETIC HEAT TARA" 1 kalori = 4,2 joule 1 joule = 0,24 kal

  20. Pemuaian • Muaipanjang: ∆f=ℓ₀α∆t • Muailuas ∆A = A₀β.∆t • Muaivolum ∆V=V₀.γ.∆t ℓt = ℓ₀(1+α.∆t) At =A₀(1+β.∆t) β=2α Vt= V₀(1+γ.∆t) γ =3α

  21. Expansion • In general, it will expand when the temperature rises. • Long expansion: ∆f=ℓ₀α∆t • Large expansion ∆A = A₀β.∆t • Volume expansion ∆V=V₀.γ.∆t ℓt = ℓ₀(1+α.∆t) At =A₀(1+β.∆t) β=2α Vt= V₀(1+γ.∆t) γ =3α
