A gas exerts pressure on the walls of the container. Identify the correct reason for the same.
Gaseous particles are hardest among the states of matter.
Gaseous particles doesn't exert pressure on the walls of the container
Gaseous particles move randomly and frequently collide with walls. Pressure is resultant of these collisions.
Gaseous particles do not move.
Pressure on the surface of a gas is increased.what will happen to the inter particle forces
When a beam of sunlight enters a room throuth a window, we can see tiny particles X suspended in a gas (or rather a mixture of gases )Y which are moving rapidly in a very haphazard manner.
(a) What could particles X be ?
(b) Name the gas (or mixture of gases) Y.
(c) What is the phenomenon exhibited by particles X known as ?
(d) What is causing the movement of particles X ?
(e) What conclusion doed the existence of this phenomenon give us about the nature of matter ?
When extremely small particles X derived from the anther of a flower were suspended in a liquid Y and observed through a microscope, it was found that the particles X were moving throughout the liquid Y in a very zig-zag way. It was also observed that warmer the liquid Y, faster the particles X moved on its surface.

A drop of ink spreads evenly throughout the water. Why?
When you use air freshener, you spray in one corner of room and it spreads to the whole room very fast. This is because

Explain diffusion of copper sulphate into water .
- high intermolecular forces of attraction among the particles.
- high kinetic energy of the particles.
- restricted motion of particles.
- all of these.

One drop of ink is added to 1000 ml of water and mixed thoroughly using spoon.
Choose the correct option about the contents of the beaker after the spoon is removed.
The beaker still has the ink particles that were added in it.
- Some of the ink particles vanish and only few of them are present in the beaker.
- All the particles of ink will be stuck to the spoon.
The beaker doesn't have any particles of ink anymore.
