When a gas jar containing air is inverted over gas jar containing bromine vapour, both bromine and air molecules move and collide with one another and...

The observation of purple colour spreads throughout the water is that the crystal of potassium permanganate is made up of many small particles and the...

Robert brown studied the movement of pollen grains suspended in water through microscope. It was found that pollen grains moving rapidly through water...

(a) Diffusion: (i) Matter is made up of tiny particles (ii) The particles of matter are constantly moving. (b) Brownian motion: (i) The pa...

(a) Diffusion; Brownian motion. (b) Diffusion. (c) States. (d) Much more. (e) Liquid; Gaseous.

Diffusion is the property of liquids and gases which tells us that their molecules moving constantly.

Diffusion is the property which brings this smell to us.

Diffusion is the property of gases which is responsible for this behaviour of perfume vapours.

False. Air also diffuses into the bromine vapour but because air is colourless. It is not visible movement.

Copper sulphate diffuses slower as compared to bromine vapour in air because the rate of diffusion is faster in gases than in liquids.

Gas diffuses faster than liquid because the particles of gases are more spacious and have high kinetic energy.

(a) LPG – Liquefied Petroleum Gas. (b) CNG – Compressed Natural Gas.

LPG (Liquefied Petroleum Gas) and Oxygen Gas are the two gases which are supplied in compressed form in houses and hospitals.

Gas is does not have a fixed shape and fixed volume.

Solid is the substance having definite shape as well as definite volume.

Gas can be easily compressed physical state of matter.

Liquid has a definite volume but no definite shape.

(a) Gases have maximum movement of particles. (b) Solids have maximum interparticle attractions (c) Solids have minimum space between particles.

(a) Solid is the rigid form of matter. (b) Liquid and Gas is the fluid form of matter.

Diffusion is the process by which a drop of ink spreads in a beaker containing water.  figure.png
