Phase Change and Temperature October 29, 2015

Bell Work Explain the diagram to the left. Be sure to include information about the molecules in the various phases and how they react during the change.

Learning Targets Students will be able to convert temperatures between Celsius and Fahrenheit.

Fahrenheit and Celsius Fahrenheit is the what people in the United States understand best. Freezing is 32 degrees Boiling is 212 degrees Celsius is the metric measurement of temperature and used by scientists Freezing is 0 degrees Boiling is 100 degrees

Formulas to convers Formula °C x 9/5 + 32 = °F (°F - 32) x 5/9 = °C

Convert Celsius into Fahrenheit 5) 50 oC = ______________ oF 6) 75 oC = ______________ oF 7) 80 oC = ______________ oF 8) 45 oC = ______________ oF Convert Fahrenheit into Celsius 9) 203 oF = ______________ oC 10) 86 oF = ______________ oC 11) 149 oF = ______________ oC 12) 158 oF = ______________ oC

Answers 5) 50 oC = 122 oF 6) 75 oC = 167 oF 7) 80 oC = 176 oF 8) 45 oC = 113 oF 9) 203 oF = 95 oC 10) 86 oF = 30 oC 11) 149 oF = 65 oC 12) 158 oF = 70 oC

Designed to show absolute zero KELVIN Designed to show absolute zero Absolute zero is the temperature where all molecular motion stop. When you give a temperature in Kelvin you do not use the words degrees and to abbreviate you use only the letter K. To convert to Kelvin you must first have your temperature in Celsius then add 273.
