Kendra knew from science class that water freezes at 0°C. She started to wonder
about the freezing points of other clear liquids. She decided to conduct an
experiment using vinegar, rubbing alcohol, and bleach. She pours 50 mL of each
liquid into three plastic containers that are all the same. She puts them in the freezer
at the same time and places the same brand thermometer in each liquid. Kendra
checks the temperatures every ten minutes and records her observations in her
journal.
