mass of a water sample

Answer 1

From a phase change diagram for water, you can obtain the following information:

• Temperature at which water freezes: The phase diagram shows the freezing point (or melting point) of water.

• Temperature at which water condenses: The diagram indicates the condensation point at which water vapor becomes liquid.

The volume of a water sample and the mass of a water sample are not directly provided by a phase change diagram.

So the correct selections are:

• Temperature at which water freezes
• Temperature at which water condenses
