The meme brilliantly parodies a phase diagram from thermodynamics, where instead of showing states of matter (solid, liquid, gas), it shows "gender states" changing with temperature and pressure.
Just like water transforms from ice to liquid to vapor as temperature increases, apparently gender follows similar principles—starting as "gender solid" (rigid, unchanging), transitioning to "gender fluid" (more flexible), and ultimately becoming "gender gas" (completely unbound) at high temperatures.
The rainbow explosion in the corner is *chef's kiss* perfect. Thirty years teaching thermodynamics and not once did I consider that gender might sublimate directly to gas under the right conditions. Someone get this to the tenure committee immediately!
