  1. How cool are you? Temperature Conversions

  2. Conversion Formulas • F = (9 · C) + 32 5 • C = K -273 • C = 5 · ( F – 32 ) 9 • K = C + 273 F = Fahrenheit C = Celsius K = Kelvin

  3. Practice • Room Temp is 21 °C. What is room temperature in Kelvin? • K = C + 273 • K = 21 + 273 • K = 294

  4. Practice • A medical thermometer registers a patient’s temperature to be 39° C. What is this in Fahrenheit? • F = (9 · C) + 32 5 • F = (9 · 39) + 32 5 • F = (351 ) + 32 5 • F = (70) + 32 • F = 102 °

  5. Practice • A popsicle melts at 78 ° F. What is this temperature in Celsius? • C = 5 · ( F – 32 ) 9 • C = 5 · ( 78 – 32 ) 9 • C = 5 · ( 46) 9 • C = 230 9 • C = 25.5 or 26 °

  6. Your turn in your journal • Liquid Nitrogen’s boiling point is 90 K. What is this temperature in °C? • The thermometer in the classroom indicates a temperature of 61 °F. What is the temperature in °C? • Convert the temperature from #2 to Kelvin. 4. The lowest temperature in Alaska in -62 °C. What is this temperature in °F?
