Answer
a. 39.167 Degrees Celcius
b. 195 Kelvin
Work Step by Step
1. Celcius = 5/9 * (Fahrenheit- 32 degrees Fahrenheit )
2. Celcius = 5/9 * (102.5-32)
3. Celcius = 39.167
4. Kelvin = (celcius* 1 kelvin/ 1 celcius) + 273.15 Kelvin
5. Kelvin =(-78 celcius* 1 kelvin/ 1 celcius) + 273.15 Kelvin
6. Kelvin = 195 Kelvin
