When a gas jar full of air is placed upside down on a gas jar full of bromine vapours, the red-brown vapours of bromine from the lower jar go upward into the jar containing air. In this experiment :

A student placed a gas jar containing air in the upside down position over a gas jar full of red-brown bromine vapours. He observed that the red-brown colour spread upwards into the jar containing air. Based on this observation, the student concluded that it is only the bromine vapour which moves up and diffuses into air in the upper jar, the air from the upper jar does not move down by diffusion into the lower jar containing bromine vapours. Do you agree with this conclusion of the student ? Give reason for your answer.

When a gas jar containing colourless air is kept upside down over a gas jar full of brown-coloured bromine vapour, then after some time, the brown colour of bromine vapour spreads into the upper gas jar making both the gas jars appear brown in colour. Which of the following conclusion obtained from these observations is incorrect ?

When a gas jar containing air is inverted over a gas jar containing bromine vapour, the red-brown bromine vapour diffuse into air. Explain how bromine vapour diffuse into air.

What happens when a jar full of H_2 gas is placed inverted over a jar containing Cl_2 gas?

A one litre flask is full of brown bromine vapours. The intensity of brown colour of vapour will not decrease apprciably on adding to the flask some.

A one litre flask is full of brown bromine vapour. The intensity of brown colour of vapour will not decreases appreciably on adding to the flask some

A one litre is full of brown bromine vapours. The intensity of brown colour of vapours will not decrease appreciably on adding to the flask some

If a gas jar filled with a light gas like hydrogen is held upside down on another gas jar filled with carbon dioxide,it is observed that the two gases produce a homogenous mixture in the jars. What is the name of this process?

One litre flask is full of brown bromine fumes. The intensity of brown colour of vapour will not decreases appreciably on adding to the flask some
