We offer data on the sublimation of dry ice (carbon dioxide) collected in a classroom setting so that students can model the rate of change in the mass of a small solid carbon dioxide block with a differential equation model, solve the differential equati Matter exists in several states: plasma, gas, liquid, and solid. When a solid becomes liquid the object melts. When a liquid becomes a gas the object vaporizes. When a solid becomes gas directly the object sublimates. A readily available exampl…
