SEP Engaging in Argument Use the phase diagrams for CO2 and H2O in the Experience Notebook. Theaters sometimes use dry ice (solid CO2) to produce dense clouds of smoke like fog on stage. A classmate claims that the phase diagrams of H2O and CO2 show that it would not be practical to use H2O for this purpose. Do you agree with the classmate’s claim? Cite reasons to support your argument.

I do agree with this statement of practicality. According to my research and viewership of phrase diagrams for both substances, water enters a similar form of “smoke” or “steam” at incredibly hot temperatures usually secluding to temperatures of over 200 degrees Fahrenheit (100 degrees Celsius) versus carbon dioxide of which enters this state at room temperature (60-70 degrees Fahrenheit). In order for either of these events to occur in this form, both must undergo procedures of sublimation where solids transfer directly from solids to gases, skipping the liquid state. Water contains ionic hydrogen bonds of which are incredibly strong particle arrangements, therefore requiring much higher temperatures to divide and individualize these particles forming high pressure and kinetic energy. Since carbon dioxide is formed of covalent bond ship, the intermolecular forces are relatively weak making the process of sublimation quite instant when this substance experiences exposure to specific temperatures, typically temperatures that we consider “normal”.

Hopefully I helped anyone understand this, and I apologize for being late to this question.....very late.
