Hello, this diagram/image has critical flaws in both its scientific accuracy and visual layout that make it misleading.

1. Confusing Visual Layout: The placement of text and values is inconsistent and confusing.
* Melting/Freezing: The value for freezing (-334) is placed directly under the "Melting" label, and the value for melting (+334) is closer to the "Freezing" label. This visually suggests the opposite of the correct pairing.
* Evaporation/Condensation: A similar layout issue exists here, with inconsistent positioning of the labels relative to the values, making the diagram hard to read correctly at a glance.

2. Incorrect Scientific Signs: The signs for two processes are factually incorrect.
* Sublimation (solid → gas) is an endothermic process and must be positive. It should be +2592 kJ/kg.
* Deposition (gas → solid) is an exothermic process and must be negative. It should be -2592 kJ/kg.

A new or corrected image is needed to fix both the confusing layout and the scientific errors. Thank you!

I see that you submitted a corrected image, so I'm going to go ahead and clear this suggestion just to avoid any redundancy.

Thank you for the suggestions, always appreciated. :-)
