animation vapour pressure liquids

Vapour Pressure of Liquids - Vapour pressure is defined as the partial pressure exerted by the vapors above the liquid surface in equilibrium with liquid at a given temperature. fig 3.3 In illustrations 1a and 1b, the h..

. In such a state, although the amount of liquid level in the vessel does not change, evaporation has not stopped and the system is not at rest. In fact, the number of molecules, which escape from the liquid to the gaseous phase (due to evaporation), becomes equal to the number ..

When a liquid is placed in an open container it disappears completely after some time. However, when the same liquid is placed in a closed container, even after a long period only a part of the liquid disappears. The obvious difference is that the vapours of ..

Pressure in a Liquid - We can investigate pressure in a liquid by using the apparatus shown in figure belo..

It is a simple pressure gauge and it measures differences in pressure exerted at the two ends of the apparatus. It is called manometer. The mouth of a thistle funnel is tightly covered with a thin plastic shee..

The Greek philosopher and mathematician of 6 t h century BC, Pythagoras proposed the idea that each organ in the body of an animal released some kind of vapour, and that the new individual is formed by the combination of vapours from different organs. Fig. 18.1 Pythago..

The vapour pressure of a liquid depends upon the nature of the liquid. When intermolecular forces are weak, the molecules tend to escape readily and therefore, the equilibrium vapour pressure is high. Vapour pressure o..

Suppose a horizontal area A (m 2 ) is supporting a column of liquid of height h (m) and density d (kgm - 3 ..
