Warm Up: {From memory} Using the formulas you learned in the lesson “3 Temperature Scales”, convert room temperature (72 F) to Celsius and to Kelvin. If you don’t remember the formula, draw a thermometer showing F and C degrees for the freezing point and boiling points of water, then compare these ranges to get the conversion factor.

Homework: Complete this worksheet temperature_conversion_wkst

Some important temperatures:

1] The coldest day in my life…..

I was living in Chicago and one January the temperature was -24F that’s right! 24 degrees below zero! Brrrrrr…………

Convert this to Celcius and to Kelvin.

2] What is Walt Disney’s body temperature?

(hint: Liquid Nitrogen boils at 77K, convert to Fahrenheit)

3] Mercury freezes at- 38.8 C. Convert to Fahrenheit.

At what temperature are Celsius and Fahrenheit degrees equal? (hint: solve the conversion formula for F/C = 1)
