Khay'lani had two substances that were both liquids at room temperature, sample A and sample B. When she removed the same amount of energy from both samples, only sample B changed phase. Why did sample B freeze into a solid while sample A stayed a liquid?
A. Sample B's molecules were moving slower
B. Sample B's molecules had a stronger molecular attraction
C. Sample A's molecules had a higher temperature
What is B or Sample B's molecules had a stronger molecular attraction?
