Vapour example sentences

We will not go into these factors in detail in this chapter, but think about this: how do the presence of the Himalayas change the flow of a wind blowing from Allahabad towards the north? The above experiment replicates, on a very small scale, what happens when air with a very high content of water vapour goes from a region of high pressure to a region of low pressure or vice versa.The stratosphere, on the other hand, contains dinitrogen, dioxygen, ozone and little water vapour.When wood or charcoal is ignited, the volatile substances present vapourise and burn with a flame in the beginning.Some amount of water exists in the form of water vapour in the atmosphere.When the number of molecules leaving the liquid to vapour equals the number of molecules returning to the liquid from vapour, equilibrium is said to be attained and is dynamic in nature.Other gases like methane, nitrous oxide and water vapour also contribute towards this effect.At equilibrium the pressure exerted by the water molecules at a given temperature remains constant and is called the equilibrium vapour pressure of water (or just vapour pressure of water); vapour pressure of water increases with temperature.Fumes are generally obtained by the condensation of vapours during sublimation, distillation, boiling and several other chemical reactions.However, this is not static equilibrium and there is a lot of activity at the boundary between the liquid and the vapour.Some of these (like calcium chloride) are so soluble that they are hygroscopic in nature and even absorb water vapour from atmosphere.When the water vapour cools down, it condenses and forms clouds.Trees take in water from their roots and release water vapour into the air through evaporation.It is a mixture of many gases like nitrogen, oxygen, carbon dioxide and water vapour.What causes the movement of air, and what decides whether this movement will be in the form of a gentle breeze, a strong wind or a terrible storm? What brings us the welcome rains? All these phenomena are the result of changes that take place in our atmosphere due to the heating of air and the formation of water vapour.Let us now consider the systems where solids sublime to vapour phase.
