How will you justify that icewater and water vapours are the three states of a substance and not substances?

This can be justified by looking at the exact chemical nature of each. Ice water, liquid water and steam (vapors) are ALLstill chemically the same, and exist as H2O, only in different states.

How can you justify that air is a homogenous mixture. Identigy substances present in it?
Air is a mixture of nitrogen oxygen co2 noble gases and water vapours
How does a fractional distillation column work?
The fractional distillation column has the mixture of substance. The mixture consists of substances which have very less difference in their boiling points . When heat is passed, the substance with lowest boiling point forms vapours. After this every substance of the mixture changes into the vapour. These vapours get collected separately and are then condensed to get separate substances
What is the gaseous form of a substance which exists as a liquid at a room temperature known as?
You think to vapours of a liquid.
A substance that exists as a solid at ordinary temperature but changes to vapour on heating?
Iodine and ammonium salts sublime, their vapours then turn back into solids when cooled down. To see the sublimation, heat some iodine in a china dish and place a funnel upside down above the vapours (violet). The heated vapours become solid on contact with the funnel wall.
What vapor colors does iodine have?
violet vapours

Does a physical change make the substance that undergoes it a different substance if not then what can change?
After a physical change a substance does not change its chemical composition it simply changes its state as, water to ice or vapours.
How is it possible to separate crude oil substances?
Through a process known as fractional distillation, also called cracking.The oil is heated and vapours of the various components are given off. The different vapours condense at different temperatures and these fractions are collected.
What are vapours?
water vapours are particles of water when water is boiled at a certain temperature the smoke you get is water vapours

Are water vapours in air charged?
water vapours changed to clouds.from vivekganandan
What is the difference between water and water vapours?
water is a liquid but water vapours is steam... when we boil water it will turn into steam which is called water vapours...
What substance is in natural gas?
natural gas mostly contains methane gas (about 94%) other 6% includes ethane , propane , butane , nitrogen and water vapours.
What is quenching in Geiger muller tube?
A small amount of vapours of a substance having low ionization potential, called as quenching gas, eg alcohol vapours, is added to gm tube, which discharges at cathode before the principle gas +ve ions which discharges at cathode in about 10^-4 seconds. So the quenching gas neutralizes itself and also the tube....
