Luna, Henry, and Oliver are studying the states of matter. They noticed that in one state, the molecules slide past each other but stay close together without forming a regular pattern. Which state of matter are they observing?

Arjun, Sophia, and Aria are conducting a science experiment. They observe that when they freeze water into ice or boil it into steam, energy is either absorbed or released.
