  • 1. GROUP 1 PowerPuffGirlz/Bo yz Application of temperature in the industry Defiinition and Conversion of Temperature Measuring Temperature Absolute Temperature Zeroth Law
  • 3. Definition
  • 4. Property
  • 5. For example, a lightening bolt can heat a small portion of the atmosphere hotter than the surface of the sun
  • 6. Tools it is measured by a thermometer, which may be calibrated in any of various temperature scales, Celsius, Fahrenheit, Kelvi n, Rankine, etc.
  • 7. Thermometers Thermocouple Pyrometer Liquid Crystal Thermometer Beckman
  • 8. Deriving the Celsius-to-Fahrenheit Conversion Formula
  • 9. CONVERSION B/W DIFFERENT TEMPERATURE SCALES 1.Determine change in T from the ice point of the given reading from its scale. 2. Convert answer in step 1 using the conversion factor of the scales. 3. Add or subtract the answer in Step 3 from the ice point of the new scale.
  • 10. Example 2 The ice point and boiling point of ⁰A are -30.0 ⁰A and +60.0 ⁰A respectively. On the other hand ⁰B has +20.0 ⁰B and +130.0 ⁰B respectively. a). Using the data, determine the number of B degrees on the B scale that corresponds to 1 ⁰A on the A scale. b). If the temperature of a substance reads +40 ⁰A on the a scale, what would the temperature read on the B scale?
  • 11. Problems
  • 12. PROBLEM 1 A pan of water is heated from 25C to 80C. What is the change in its temperature on the Kelvin Scale and on the Fahrenheit scale?
  • 13. A time and temperature sign on a back indicates that the outdoor temperature is - 20C. Find the corresponding temperature in the Fahrenheit scale. PROBLEM 2
  • 14. During a heating process, the temperature of a system rises by 10C express the rise in temperature in Kelvin and Fahrenheit. PROBLEM 3
  • 15. You place a small piece of melting ice in your mouth eventually the water converts from ice at T1=32F to body temperature T2=98.6F. Express these temperatures as Celcius and Kelvin, and find change in T in both cases. PROBLEM 4
  • 17. Definition Absolute zero is the coldest possible temperature. It is the temperature at which entropy reaches its minimum value.
  • 18. 0K Kelvin 0 R Rankine −273.15° Celsius −459.67° Fahrenheit Absolute Zero Standards
  • 19. Scientists have achieved temperatures extremely close to absolute zero, where matter exhibits quantum effects such as superconductivity and superfluidity
  • 20. ZEROTH LAW
  • 21. It deals with the concept of thermal equilibrium. Definition
  • 22. Two systems are said to be in thermal equilibrium if there is no net flow of heat between them when they are brought into thermal contact.
  • 23. Then, temperature is the indicator of thermal equilibrium in the sense that there is no net flow of heat between two systems in thermal contact that have the same temperature.
