Question

read the scenario. what is the dependent variable? scenario: a student wanted to test the hypothesis, \if the amount of antifreeze added to water increases, then the freezing point of water will decrease.\ the student set up two beakers with the same amount of liquid in each one. beaker a had 100% water. beaker b had 50% water and 50% antifreeze. both beakers were placed in a freezer with a thermometer in them. it was determined that beaker a froze at 0°c and beaker b froze at -20°c. the student repeated the experiment two more times using the same set up.

Explanation:

In an experiment, the dependent variable (DV) is what is being measured or observed and depends on the independent variable. Here, the independent variable is the amount of antifreeze added. The hypothesis predicts how the freezing point of water changes with the amount of antifreeze. So the freezing point of water is what is being measured (it depends on the antifreeze amount), making it the dependent variable.

Answer:

The dependent variable (DV) is the freezing point of water.
