TEMPERATURE• Fahrenheit (oF)• Celsius (oC)• Kelvin (K)
TEMPERATURE IS…
Is a measure of average energy of motion of the particles of a substance.
The higher the temperature = the faster the particles are moving
The lower the temperature = the slower the particles are moving
Tool for measuring = thermometer
UNITS OF MEASURE
Fahrenheit or oF
Celsius or oC
Kelvin or K
All positive numbers
Easier to work with
0 K= absolute zero
The point when all motion stops
CONVERSION FORMULAS:
Fahrenheit Celsius oF= (1.8 x oC) + 32
Celsius Fahrenheit oC= .556 x (oF – 32)
Kelvin Celsius K= oC + 273
Celsius Kelvin oC = K - 273
EXAMPLES What is 45oF in oC? Formula= oF = (1.8oC X oC) + 32
What is 42oC in oF? Formula= oC= .556 x (oF -32)
What is 60oC in K? Formula= oC = K – 273
What is 50 K in oC? Formula= K = oC + 273
YOU TRY (SHOW YOU WORK!) Work with your partner, then check with your table
35oF = _____ oC
72oC = _____ oF
345 K = _____ oC
67oC = _____ K
56oF= ______K
491K= ________oF
