In 933, the islands were granted to William I Longsword by Raoul King of Western Francia and annexed to the Duchy of Normandy. In 1066, William II of Normandy invaded and conquered England, becoming William I of England, also known as William the Conqueror. In the period 1204--1214, King John lost the Angevin lands in northern France, including mainland Normandy, to King Philip II of France, but managed to retain control of the Channel Islands. In 1259, his successor, Henry III of England, by the Treaty of Paris, officially surrendered his claim and title to the Duchy of Normandy, while the King of France gave up claim to the Channel Islands, which was based upon his position as feudal overlord of the Duke of Normandy. Since then, the Channel Islands have been governed as possessions of the Crown and were never absorbed into the Kingdom of England and its successor kingdoms of Great Britain and the United Kingdom.

Condensation is the change of the physical state of matter from gas phase into liquid phase, and is the reverse of vapourisation. The word most often refers to the water cycle. It can also be defined as the change in the state of water vapour to liquid water when in contact with a liquid or solid surface or cloud condensation nuclei within the atmosphere. When the transition happens from the gaseous phase into the solid phase directly, the change is called deposition.
is condensation of water vapor a physical change?

In general, the more massive a star is, the shorter its lifespan on the main sequence. After the hydrogen fuel at the core has been consumed, the star evolves away from the main sequence on the HR diagram. The behavior of a star now depends on its mass, with stars below 0.23 M becoming white dwarfs directly, whereas stars with up to ten solar masses pass through a red giant stage. More massive stars can explode as a supernova, or collapse directly into a black hole.
do all stars spend the same amount of time on the main sequence?
