2. Notes: (chapter 2.7) 3 different scales for temperature Celsius (metric system) Fahrenheit (used by US and GB, confusing) Kelvin (used by chemists and physicists) We will be using Celsius and Kelvin, but you should be able to convert from anyone of them to any other.

3. Calculations Celsius to Kelvin (or back) C + 273 = K Celsius to Fahrenheit (or back) 1.80(C) + 32 = F

4. Practice problems (K and C) 1. 200 K is how many degrees C? 2. 0 K is how many degrees C? 3. 1930 C is how many degrees K? 4. -436 C is how many degrees K?

5. Practice problems (F and C) 1. 10 degrees F is how many degrees C? 2. 68 degrees F is how many degrees C? 3. -10 degrees C is how many degrees F? 4. -145 degrees C is how many degrees F?

6. Practice problems (F and K) 1. 10 degrees K is how many degrees F? 2. 601 degrees K is how many degrees F? 3. -15 degrees F is how many degrees K? 4. 1100 degrees F is how many degrees K?
