Mean cannot be determined by graphical method.
Mean is the sum of the values of a subject divided by number of values.
As it is a single value and cannot be compared and represented in different values the determination of mean by the graphical method is not possible.
Mean is a perfect method for the determination of the central tendency of a value.

Mr. Nath, was a neighbor of the children at Shankar House. He lived alone, kept to himself and often sought medical treatment from the children's mother. We do not have any clear evidence on the character of Mr. Nath, who had mixed reviews from the neighbors, who thought he was quite rude and mad, while Nishad and his mother, thought Mr. Nath was a harmless man and rather polite. The reader is free to make any assumptions on Mr. Nath, provided they are logical and well-backed by facts from the story.

Properties of solids
- Solid has fixed volume.
- Solid has fixed shape.
- Solid has high density.
- Solids are heavy.
- Solid does not flow.
Properties of liquid
- Liquid has definite volume.
- Liquid has no definite shape.
- Liquid gets the shape of container in which it is kept.
- Liquid cannot be compressed much.
- Liquid has less density compare to solid.
- Liquid is lighter than solid.
- Liquid flows and hence is called fluid.
Properties of gas
- Gas has indefinite shape
- Gas has no fixed volume.
- Gas gets the shape and volume of container.
- Gas fills the container completely.
- Gas has very low density.
- Because of low density gas are light.
- Gas can flow easily and hence are called fluid.

When a capacitor is charged by a battery, work is done by the charging battery at the expense of its chemical energy. This work is stored in the capacitor in the form of electrostatic potential energy.
Consider a capacitor of capacitance C. Initial charge on capacitor is zero. Initial potential difference between capacitor plates = zero. Let a charge Q be given to it in small steps. When charge is given to capacitor, the potential difference between its plates increases. Let at any instant when charge on capacitor be q, the potential difference between its plates V=q/C

Now work done in giving an additional infinitesimal charge dq to capacitor
dW = V dq = q/C dq
The total work done in giving charge from 0 to Q will be equal to the sum of all such infinitesimal works, which may be obtained by integration. Therefore total work

Ferrous sulphate crystals contain water molecules as water of crystalisation - (FeSO4. 7H2O).
On heating, ferrous sulphate crystals lose water and anhydrous ferrous sulphate (FeSO4) is formed.
Due to this, it's colour changes from light green to white.

Apartheid- It was the policy of social discrimination followed in South Africa. This policy divided the people and labelled them on the basis of their skin colour. Under this system, blacks were forbidden from living in white areas. Trains, buses, hotels, hospitals, schools and colleges, libraries, cinema halls, public toilets, etc. were all separate for white and blacks. In South Africa, white did not give equal rights to the native Africans.
India had raised this issue first time in United Nations General Assembly in 1946.
It was due to the constant moral support of India and the continuous struggle of Dr. Nelson Mandela, the policy of apartheid has been abolished in South Africa in 1990.

| Size of the particles | < 1nm | 1– 1000nm | >1000nm |
| Nature | Homogeneous | Heterogeneous | Heterogeneous |
| Filterability(Diffusion through parchment paper) | Particles of true Solution diffuse rapidly through filter paper as well as parchment paper. | Colloidal particles pass through filter paper but not through parchment paper. | Suspension particles do not pass through filter paper and parchment paper. |
| Visibility | Particles of True Solution are not visible to naked eye. | Colloidal particles are not seen to naked eye but can be studied through ultra microscope. | Suspension particles are big enough to be seen by naked eye. |
| Tyndall effect | True Solution does not show Tyndall effect. | Colloids shows Tyndall effect. | Suspension may or may not show Tyndall effect. |

Different properties of solutions are as follows:
- It is a homogeneous mixture.
- Its particles are too tiny and have a diameter less than 1 nm.
- The particles are not visible to naked eyes.
- Particles don’t scatter a beam of light passing through it and hence the path of the light is not visible.
- Solutes are inseparable from the mixture and do not sediment. A solution is stable.
- The components of a mixture cannot be separated using filtration.
