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
