Three Temperature Scales
1. In what ways are the three temperature scales the same? In what ways are they different?
2. What is a Kelvin?
3. What are the freezing and boiling points of water on each scale?
4. The normal temperature of the human body is 98.6°F. What is this temperature on the Celsius
scale? On the Kelvin scale?
6. Why is zero considered to be a relative value on the Celsius scale and an absolute value on the
Kelvin scale?
7. The liquid in one container drops 100°F, while the same liquid in another container drops 100°C.
How does the change in thermal energy in the two containers compare? Explain your answer.
8. At approximately what temperature would Celsius and Farenheit thermometers register the same
reading?
