Once the water is boiling, the temperature probe remains at a steady 100ºC.

Sketch the hand-drawn temperature/time graph they discuss after the experiment.

How many segments are there in the line?

Why did the girls' water boil at only 99ºC?

What is the boiling point at the top of the mountain shown?

How can you get water to boil at temperatures above 100ºC?

What do you call it when a solid goes directly to a gas without being a liquid?

How does a freeze-dryer work?

The chemist grows small crystals of iodine on the bottom of a flask.  What is this process called?

Look at the heating curve graph for iron.  How is it different from water's?
