Stacy reads that a 50: 50 mixture of methanol and water is best for keeping a car’s radiator from freezing when the temperature goes down to –40°c. design an experiment to test this finding. you have a –40°c freezer, water, methanol, graduated cylinders to measure volume, several plastic beakers, and a watch at your disposal. be sure to state your hypothesis, procedure, and any controls in your experiment. what are the dependent and independent variables? explain the possible results if your hypothesis is true.
