properties of liquids in different changes

Boiling - Vapour pressure measures the tendency for the molecules to escape from liquid to the gas phase. At lower temperatures the vapour pressure of a liquid is much lower than the pressure on the surface of the liquid. When the temperature of the liquid is..

Liquids have a definite volume under given temperature and pressure conditions. Though they take the shape of the container, they maintain their volume. The intermolecular forces in liquids are strong and therefore, they do not expand to occupy all the space available (as ..

-tube. When the pressure exerted on the plastic sheet is greater, the difference in the levels (h) is also greater. This difference is the measure of the difference in the pressures at the two ends of the manometer. Now, lower the mouth of the funnel into a glass vesse..

A physical change is one in which the shape, size, appearance or state, of a substance may alter, but its chemical composition remains same. No new substance is formed. It is usually a change, which is reversible. By reversing the process, the original substance can be obtained...

A compound cannot be separated into its constituents by mechanical or physical means. For example, if we bring a magnet near a sample of iron sulphide, the iron present in the iron sulphide cannot be separated . Properties of a compound differ entirely from those of its con..

Liquid-Gas (vapour) Equilibrium - 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 ..

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 liquid state lies between the gaseous and the solid state. Liquids are neither completely disordered nor completely ordered. The cohesive forces between the liquid particles are strong enough to keep them together but these particles do not occupy fixed lattice sit..
