Is dry ice an example of thermodynamics?

Answer 1

Yes. Dry ice demonstrates equilibrium between solid and gas. Thermodynamics predicts that such an equilibrium should be possible. It also demonstrates that transition from solid to gas need not include a liquid phase in between - again predicted by thermodynamics.

Answer 2

Dry ice is an example of thermodynamics in action, as it undergoes sublimation from a solid to a gas at temperatures above -78.5°C without going through the liquid phase. This process involves the transfer of energy as heat and is governed by thermodynamic principles.
