A student wants to test if adding antifreeze to water lowers its freezing point. What is the dependent variable?

• Amount of antifreeze added

• Temperature at which mixture freezes

• Type of thermometer used

• Amount of water in container

A student found that pure water froze at 0°C, and water with antifreeze froze at -20°C. To confirm the results, the student should repeat the experiment using -

• a different amount of antifreeze

• a different amount of water

• exactly the same set-up as the first experiment

• a container of a different size
