A student collected the data shown in the table below during an experiment. Liquid Characteristics Liquid Characteristics Boiling Point Freezing Point Color Toxicity Mercury 357 °C −39 °C shiny silver gray hazardous if tube is broken Alcohol 78 °C −115 °C colorless relatively non-hazardous Based on the data, which of the following conclusions can be made about the use of mercury and alcohol thermometers? An alcohol thermometer can easily measure the boiling point of a colorless liquid that boils at 100 °C. A mercury thermometer can easily measure the boiling point of a colorless liquid that boils at 82 °C. A mercury thermometer can easily measure the freezing point of a colorless liquid that freezes at −50 °C. An alcohol thermometer can easily measure the freezing point of a colorless liquid that freezes at −110 °C.
