in an experiment, a science class filled a plastic bottle with room temperature olive oil and placed it in the freezer for two hours. when the bottle was observed at the end of two hours, the volume of the oil had decreased, which caused the bottle to contract. what happened? group of answer choices
the particles in the olive oil lost energy as they cooled, became more densely aligned, and took up less volume.
