how would you identify the test variable (independent variable)?
the type of liquid.
the time it took for the liquids to freeze
the amount of water in each container.
the amount of salt in each container.

Explanation:

The independent variable (test variable) is the factor that is deliberately changed in an experiment. In an experiment about liquids freezing, the type of liquid can be deliberately chosen and changed, while the time it takes to freeze is the dependent variable and the amount of water/salt are likely controlled variables.

Answer:

The type of liquid.
