(1) we observed water droplets at the outer surface because of the latent heat of vaporization, the water vapours present in environment stick on the cold surface.
(2) solid have strong force of attraction b/w the atoms while this force is negligible in liquid an gaseous state.
(3) At a higher altitude, the atmospheric pressure is lower ,so water boils faster tahn pressure cooker prevents from boiling water so that food can be cooked properly.
(4) the property of a substance to flow is called fluid.
(5) because at the room temperature the force b/w hydrogen and oxygen is weak.the molecules are not tightly packed
(6) this is because the cotton fibre has the small holes in which oxgwn is trapped which make it floatable.
(7) this is because of the strong force of attraction b/w the particles of solid ,this force is weak in liquid and gas.
(8)# atmospheric pressure
#temperature
#movement of winds.
(9) compressible property of gas is useful in filling LPG cylinders in liquid state to cook food.
Sorry I can give u Answer and I'll answer those latet

6) Rayon resembles both the properties of natural silk as well as appears to be artificial fibre.
7) pvc(poly-vinyl chloride) or backelite is used.
8) CFC(chloro fleuro carbon).
9) As the are noble metals and do not react with other gases or metals except some.
1) As the container containing ice is much lowered temperature than the atmosphere so the water droplets present in the atmosphere gets accumulated over it.
2)solids hve less or negligible intermolecular space high intermolecular force of attraction compared to liquid and gases so they have fixed shape.
3) As in high altitudes have low temperature and less oxygen so it is better to use pressure at high altitudes.
4) Substances that flows that are liquids and gases.
5) At room temperature the intermolecular force of attraction decreases and the intermolecular spaces increase between the water particles so it becomes liquid.
6) cotton being solid appears like sponge and absorbs water. It is lighter than water and hve more volume than water. So it floats on water
7) Solids hve high intermolecular force of attraction and less intermolecular spaces so they are more denser than liquids or gases.
8)temperature, surface area, humidity, altitude and nature of liquid.
9)this property is used to make dry ice that is made by compressing gaseous carbon dioxide at high temperature and pressure.
10) this property is essential in case of the oxygen that gets dissolved in water and is helpful in case of aquatic organism
