Solution: Phase changes and the names associated with them.How is energy evolved in deposition related to those for condensation and freezing?

Problem

A diagram has energy on the y-axis, (increasing and unscaled). Gas is highest energy, followed by liquid and then solid (lowest energy). Phase change from solid to liquid occurs by melting or fusion and is an endothermic process (energy is added to the substance). Phase change from liquid to solid occurs by freezing and is an exothermic process (energy is released from the substance). Phase change from solid to gas occurs by sublimation and is endothermic, while phase change from gas to solid occurs by deposition and is exothermic. Phase change from liquid to gas occurs by vaporization and is endothermic, while phase change from gas to liquid occurs by condensation and is exothermic.
