The main thing which the feudal system was based on was land ownership.
<h3>What is Feudalism?</h3>
This refers to the social system that was mainly used in medieval Europe where a lord gave land to his vassals as a reward,
Hence, we can see that your question is incomplete so a general overview of the feudal system was given to help you get a better understanding of the concept.

Answer:
According to my experience, revising the chapters before 1 month would really be beneficial. If you have the habit of following time table then you can make one and set the target to finish the syllabus right 3 or 4 days before examination which would make you feel confident. Find your distraction factor and try your best to avoid it. Practicing maths at night and reading the other subjects at morning will be more suitable. You can write the things on your rough copy which would really help you to memorize for language subject. And for maths you may start from the easy questions and you may go to difficult ones. That will help you somehow to develop interest. Dont choose a place like bed to study. Sit in such place where you won't feel sleepy. Dont feel pressurize while reading.
You learn new thing every day!!!
Explanation:
Answer: arrange a number of given straight-chain alkanes in order of increasing or decreasing boiling point or melting point.
arrange a series of isomeric alkanes in order of increasing or decreasing boiling point.
explain the difference in boiling points between a given number of alkanes.
Explanation:Table 3.5.1 describes some of the properties of some straight-chain alkanes.
There is not a significant electronegativity difference between carbon and hydrogen, thus, there is not any significant bond polarity. The molecules themselves also have very little polarity. A totally symmetrical molecule like methane is completely non-polar, meaning that the only attractions between one molecule and its neighbors will be Van der Waals dispersion forces. These forces will be very small for a molecule like methane but will increase as the molecules get bigger. Therefore, the boiling points of the alkanes increase with molecular size.
For isomers, the more branched the chain, the lower the boiling point tends to be. Van der Waals dispersion forces are smaller for shorter molecules and only operate over very short distances between one molecule and its neighbors. It is more difficult for short, fat molecules (with lots of branching) to lie as close together as long, thin molecules.
The boiling points shown are for the "straight chain" isomers of which there is more than one. The first four alkanes are gases at room temperature, and solids do not begin to appear until about C17H36 , but this is imprecise because different isomers typically have different melting and boiling points.
