Hey student,

I hope you are doing good.

I hope it helps.

Dear Student,

The word Electrophile, is made up of two words. The one is Electro which means electron and the second word is Phile which means liking/loving. Overall the word Electrophile refers to the species which likes electrons. By this , we means that, in a chemical reaction the electrophile species gets attracted towards an electron. Hence an Electrophile should be regarded as an Electron liking/Loving species.

Hope this helps.

Hello Sangita Kumari!

Before getting into the exact answer, a few things to say!

1. Mechanics is the basics of physics. It includes linear motion, laws of motion, rotational motion etc. It is not related to electricity or optics.
2. I would recommend you to study optics and then waves. because some of the basic concepts of optics such as wavelength, frequency etc also appear in waves. You can also simultaneously study them if that is comfortable for you.
3. Then for electricity part, electrostatic is the basic chapter and a proper understanding of it will help current electricity chapter.
4. Then you can study Magnetism and electromagnetic induction.
5. Thermodynamics can be covered in between.

So I would the sequence mechanics, electrostatic, current, magnetism, electromagnetic induction, thermodynamics, optics and waves.

Note that this is my opinion. I f you feel any other sequence comfortable go with that. Remember that while you are covering a new chapter you must regularly revise the previous chapters.

All the best!

Hello there

You have given me a really tough job though as no one can predict that from which sections jee advanced gives more questions .

Okey for chemistry if you have left the physical chemistry then you will still be able to  clear the cutoff for chemistry ( you must know that you have to score a minimum marks in each subject individually ) for maths portion the portion you have told is quite less .The calculus part carries a lot of marks so can't be left in order to get qualified .

For physics ,jee advanced usually prepares questions which caries concepts from multiple chapters so you must know the theory of most of the chapters ,however you can avoid doing much questions

Practice wisely and be consistent and keep working hard

Best wishes

Hi Kasini,

Molar heat capacity is usually given in kJ/molK which basically means how much energy you need to raise the temperature of 1 mole of substance by 1K.

The molar heat capacity of water at constant pressure is 75 J K^−1 mol^−1

Feel free to ask doubts in the Comment Section.

I hope this information helps you.

Good Luck!

Hello aspirant!!

If u wish to revise 11th class thermodynamics, it is a good desision. It will help you to build strong concept for further studies and will give your deep rooted knowledge about this subject.

Hope you find this useful.

Hello Aryan,

The second law of thermodynamics states that the total entropy of an isolated system can never decrease over time, and is constant if and only if all processes are reversible. Isolated systems spontaneously evolve towards thermodynamic equilibrium, the state with maximum entropy.

Hope it clears your doubt.

Thank you!

Viscosity is a measure of a fluid's resistance to flow. It's a physical property of fluids. In simple words, viscosity shows resistance to flow. Some liquids with low viscosity are- Water, Ether, Chloroform, Acetone etc. Most of the low viscous fluids are non polar with mow intermolecular forces. High viscosity means that the friction between two layer is high. So the liquid will flow slowly. For example, Vegetable oil, mercury, glycerin and many more.
