Phase changes of water - Oakland Schools

Observations:
1. Describe the temperature vs. time graph. Are some parts sloped differently than
others?
2. A chemistry book writes H 2 0 (s), H 2 0 (l), and H 2 0 (g). What do the letters in the
parentheses mean?
3. At ordinary atmospheric pressure, what is the highest temperature that liquid water
can reach before it boils? Your data from Table 1 should show you this. Compare your
results with the rest of the class and figure out the average value.
