Which experimental design would be best to use in investigating the boiling points of water and ethanol?(1 point)A. Mix samples of water and ethanol in a beaker, then heat using a Bunsen burner. Measure the temperature at which the sample boils using a thermometer. Record this temperature as the boiling point.B. Heat samples of water and ethanol in two separate beakers using a Bunsen burner. Measure the temperatures at which the samples boil using a thermometer. Record these temperatures as the boiling points.C. Heat samples of water and ethanol in two separate beakers using a Bunsen burner. Measure the temperatures at which the samples boil using a thermometer. Conduct several trials and record the average temperatures as the boiling points.D. Mix samples of water and ethanol in a beaker, then heat using a Bunsen burner. Measure the temperature at which the sample boils using a thermometer. Conduct several trials and record the average temperature as the boiling point.
