Fractional distillation is used in petroleum industry to separate different fractions of crude oil.

1. Mixture of acetone (b.p. 329 K) and methyl alcohol (b.p. 337.7 K)

2. Mixture of acetone (b.p. 329 K) and benzene (b.p. 353 K)

If in a mixture, the difference in boiling points of two liquids is not appreciable/large, they cannot be separated using simple distillation. 

To separate such liquids, fractional distillation is used.

Correct option is  A) E = hυ

Correct option is  C) P, Q and R

1. Sponge: gemmule 

2. Algae or fishes or amphibian

Correct answer is (b) two

Answer 1.  2

Answer 2. 8

The volume of an orbital i.e. probable density is much smaller than the shell of an atom. 

The element is Ti (Titanium). Its electronic configuration is 1s²2s²2p⁶3s²3p⁶4s²3d².

Reason : 

1. Electrons enter M shell after completion of K and L. 

2. So the number of electrons in M shell is 10. 

3. But after completion of 3p orbital electron enters 4s before entering to 3d. 

4. So outermost orbit or shell is N shell. 

5. So the atomic number of element is 22.

6. Its electron configuration is 1s² 2s² 2p⁶3s² 3p⁶4s² 3d².

The probable density of an electron in s-orbital is equally distributed at all coordinates in space. 

C) maximum, minimum

C) Max Planck

Correct answer is

(B) both the genes are expressed equally

Some other ways in which we can send invitation to our family and friends are as follows:

5. Through courier.

1. The Leaning Tower of Pisa may be straightened. 

2. Cars will be travelling through air rather than by road. 

3. People might make trips to the moon for a vacation. 

4. We could have floating homes on water. 

5. People would be skating or cycling to their place of work.

The modal verbs in the above sentences are:

• may
• will 
• might 
• could 
• would Let us do some more:

Cycles, cars, trucks, trains, aeroplanes, carts, watches, toys, our National Flag, chair, table, trolley, skateboard, motorbike, bags, vacuum cleaner, baby carriage.

I cannot imagine life without wheels. Things would all be done at a very slow pace. There would be no technological development and we would not have reached the moon and other places without wheels.

Though the wheel was made during the Stone Age period, it was the beginning of a revolution. Wheels helped the early man to transport goods from one place to another and thus began trade. Wheels moved slowly at first and caught momentum. Today we have progressed so far just because of wheels that is why I think the wheel is very important in human civilisation.

This was said by Rohan out of fear and frustration having gone through an unexpected turn of event in the middle of the night.

The examples of man’s progress given in the poem are – radio, motor cars, street lights, telegraph and the telephone.

The awareness and sensitivity of co-passengers matter a lot in the sad incident of Arunima. If co-travellers were sensitive and courageous, unitedly they could have scared the thugs attacking a single, helpless young girl.

Secondly, armed railway policemen should be deployed almost in each compartment to deal with such situations. Thirdly, digital surveillance should be installed in almost each compartment to observe the goings-on inside. If something wrong is observed, immediate help should be rushed.

Once while Arunima was travelling by a train and was dozing on her berth, she felt a hand tugging her gold chain. She woke up and saw four or five desperate young men surrounding her. All were drunken and no help was possible, so Arunima had to fight them.

One of the robbers kicked her hard and she lost her balance and flew out of the train. In midair she was rebounded by another train on the next track. The ping- pong went on and finally she fell down unable to recollect her leg from the track and lost it for ever.

1. publicity 

2. prominently

Arunima lost one of her legs in an unfortunate incident, but it never affected her spirit. Her dream was to scale Mt. Everest. An artificial leg was fitted and she rose once more to fulfil her dream.

It was almost impossible for a mountaineer to climb with only one leg, still she did not lose courage and went on trying to scale different heights and collected enough confidence to reach her goal. Finally she could manage to be at the top of the world. Thus, she literally followed the quote of Swami Vivekanand and proved it to be worth practising.

Arunima had lost her leg in the accident. On the intervention of the PM, she was admitted to AIIMS, Delhi. The union government bore the entire cost of her treatment.

AIIMS began issuing daily medical bulletin on her status. Young people, auto-drivers and roadside vendors carried out candle march to galvanize support for her and to pray for her recovery. Thus she got very warm support from various fronts.

Their school is setting new trends in Activity based learning.

Mr. Shashank, Newspaper Editor, was invited to cover the function prominently.

Had I been In the train compartment near Arunima. I would have sneaked to the other passengers and pleaded them to fight against the thugs. If all of them had come together and attacked the thugs. we could have saved Arunima from being thrown out of the train.

A note of it has been made by me.

Yes, it is a good idea to cover such programmes done for a noble cause in the newspaper, as it sets a trend for other schools to follow and children also become aware of their social responsibilities.

1. Sending them sweets on festive occasions. 

2. Collecting funds and contributing it towards various initiatives organised by soldiers. 

3. Visiting them and organising cultural programmes for them. 

4. Writing letters to them and expressing our gratitude to them for giving us a sense of security. 

5. Inviting them to the school on occasions like Independence Day, Republic Day etc., and deriving inspiration from their words of wisdom.

Through the above lines, the poetess is conveying the message that if she can reduce the pain and suffering of anyone in this world, her life will acquire meaning. It will be a purposeful life, well-lived.

to sit – infinitive.

(a) one – won (b) pain – pane.

Woodrow Wilson has rightly said, “There is no higher religion than human service.” To work for the common good is the greatest creed.

Our life acquires meaning only when we commit it towards the service of others. Love, care, compassion, kindness, empathy, sympathy, etc., are some of the vital values which will help us to reach out to those in need or to those in distress. There are several social workers who have committed their life in service of others. Whether it is Mother Teresa, Baba Amte, or Sant Cadge Maharaj, one thing they had in common was the unconditional love they had for their fellow beings.

We can make a world of difference by joining NGOs or participating in our school’s initiatives towards social work. Visiting home for the aged and spending time with the elderly, distributing gifts to the children in orphanages on our birthday, etc., are little acts of kindness which can make a big difference. 

Let us remember the words of Mahatma Gandhi: “The best way to find yourself is to lose yourself in the service of others”. With a heart filled with generosity, with words that are kind and through acts of selflessness, let us build a world where love and happiness reign supreme.

Begining with getting comfortable in the author’s house, caesar slowly started annoying the pets already there. He would tug at the tail of one of the dogs or sit on top of Harold, the hornbill’s cage and peck his feet and annoy him. This trait makes me laugh.

When Aunt Mabel paid the author a visit, Caesar impressed her by landing on her arm and demanding a kiss. As soon as Aunt Mabel (all delighted. put her cheeks forward, her spectacles grabbed his attention and he knocked them off.

Caesar on one hand is a very snobbish and mischievous crow troubling the Hornbill and not mingling with other crows. But on the other hand, he comes across as a very loving bird greeting the writer and kissing him. Yes, I think all animals and birds have these contrasting traits just as we humans do. They are good to some people and mischievous with the ones who don’t like them.
