Question

A student sets up an experiment to determine how much time will elapse before equal samples of water at 20°C become solid if placed in freezers at four different temperatures. Which are the independent and dependent variables in this experiment? A. the starting temperature of the water, and the water containers used B. the starting temperature of the water, and the time it takes the water to freeze C. the various temperatures in the freezers, and the water containers used D. the various temperatures in the freezers, and the time it takes the water to freeze

Answer 1

D. the various temperatures in the freezers, and the time it takes water to freeze

Step-by-step explanation:

The dependent variable is the variable in an experiment that is subject to being tested and put under observation.

The independent variable is the variable that is changed and altered in order to bring certain effect on the dependent variable.

The various temperatures in the freezers is the independent variable that is subject to change and alteration while the time it takes water to freeze is the dependent variable.
