Question 11.1.1: Investigate phase changes. In the figure below, N is blue an......

You are asked to identify the type of physical change and the energy change that happens during a phase change.
You are given a molecular-level illustration of a phase change.
The figure represents a physical change because the NH_{3} molecules are intact in both boxes. The change is from a gas on the left to a solid on the right, a process called deposition. Deposition is a change from a less ordered phase to a more ordered phase, so energy is released.
