The image shows the drawing a student made of ice molecules observed through an electron microscope.

Is the student's drawing correct?

• Yes, because the molecules in the solid state are arranged randomly and move randomly relative to each other.

• No, because the molecules in the solid state are arranged in ordered arrays and do not move much relative to each other.

• No, because the molecules in the solid state are arranged in ordered arrays and move randomly relative to each other.

• Yes, because the molecules in the solid state are arranged randomly and do not move much relative to each other.
