One student filled two clean jars with hot water. Baking soda was added to water in both the jars and stirred until no more baking soda dissolved in the water. Small weights were tied to two ends of a thread and the ends were dipped into the two jars as shown below. (1 point) An illustration depicting two glass jars filled with water.
