The two changes of state involved in freeze drying are melting and freezing.
In order to know what two changes of state are involved in a process one needs to know what the process is.
"The" two changes are wrong. There are lots of different states of matter, and therefore many different possible transitions. The most commonly studied states of matter are solid, liquid, and gas; each of them can change directly to each of the others, for a total of 6 types of change.
Factors that affect changes in matter include temperature, pressure, and the presence of catalysts. Changes can also be influenced by the amount of reactants present, the surface area of the substances involved, and the concentration of the substances. Additionally, the type of chemical bonds in the substances can determine how easily they undergo changes.
You can determine if a chemical reaction is occurring by observing changes in the physical or chemical properties of the substances involved. Two methods to identify this process are observing the formation of a precipitate or a color change in the reaction mixture.
All the reactions in a path are added together.
The two changes of state involved in freeze drying are melting and freezing.
There were about 300 city-states involved, led by Athens and Sparta.
Kansas and Nebraska
The two changes of state involved in freeze drying are melting and freezing.
The two countries were America and Russia.
Throughout the Peloponnesian War the city - states of Athens and Sparta were the two leaders.
Russia and United States.
In distillation, two physical changes involved are evaporation (liquid turning into vapor due to heat) and condensation (vapor turning into liquid when cooled). The process separates components based on their different boiling points.
Karnataka and Tamil Nadu

Results of the war between Britain and the United States involved no geographical changes, and no major policy changes. However, all of the causes of the war disappeared at the end of the war between Britain and France. Also, with the destruction of the power of tribes, Americans no longer feared the Indians.
