How can particle interactions explain the properties and behavior of dry ice?

Dry ice is the solid form of carbon dioxide (CO2). The particle interaction in dry ice is due to collision between inter-particles which results in agglomeration and shows the properties and behavior of dry ice.

The inter-particle collision in dry ice keeps the high temperature of dry-ice and make it sublimate (solid to gas) at room temperature and normal pressure.

The collision of carbon atoms in dry ice also makes it highly reactive and shows chemical properties of dry ice. When dry ice is added with magnesium, it left black powder, which is carbon

in 1859, charles darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. he defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved".
