How does Victor's mood change each time the setting changes in "Frankenstein"? I mean how is Victor attitude, health etc. when he goes to Geneva,...

Shelley's imagery helps to create the setting.  When the setting is calm and relaxed (while Victor is at home and when he is in the mountains), Victor finds himself mirroring his surroundings.  He, too, is calm and rejeuviinated when he is surrounded by nature, just like the plants and trees themselves.  When he is in his laboratory, the weather is described as dark and dreary, again mirroring Victor's internal conflict.  He struggles to complete his creation, and when he finally does (after two years), he promptly runs out on it.  Storms throughout the novel reflect the inner storms of both Victor and the Creature.  It is fitting that the final battle should take place in the Arctic where it is cold and there is little life sustained.
